    UNITED STATES,

    v.
    REYNALDO LANDRÓN-CLASS,
    Defendant, Appellant.
    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF PUERTO RICO
    [Hon. Francisco A. Besosa, U.S. District Judge]
    Before
    Lynch, Chief Judge,
    Selya and Lipez, Circuit Judges.
    Rafael F. Castro Lang for appellant.
    Scott H. Anderson, Assistant United States Attorney, with whom
    Rosa Emilia Rodriguez-Velez, United States Attorney, Nelson Pérez-
    Sosa and Thomas F. Klumper, Assistant United States Attorneys, were
    on brief, for appellee.
    August 29, 2012
    LIPEZ, Circuit Judge. Appellant, Reynaldo Landrón-Class,
    was tried and convicted in the United States District Court for the
    District of Puerto Rico for his role in a scheme to illegally
    obtain and distribute prescription drugs. On appeal, Landrón-Class
    challenges his conviction on numerous grounds, including: 1) a pre-
    trial ruling during the voir dire, 2) evidentiary rulings made by
    the district court during his trial, 3) the court's decision not to
    order certain documents turned over to him as Jencks Act material,
    and 4) the denial of his motion for a judgment of acquittal under
    Federal Rule of Criminal Procedure 29.          He also asserts multiple
    errors in the determination of his sentence.
    We conclude that the district court did err in allowing
    testimony   about   the   guilty   pleas   of   appellant's   former   co-
    defendants; however, this error was harmless.          Additionally, in
    resolving a claim of sentencing error, we join other circuits in
    holding that, in determining the appropriate sentence within the
    guidelines, or in varying from the guidelines, a sentencing court
    has discretion to consider the defendant's cooperation with the
    government as an 18 U.S.C. § 3553(a) factor, even if the government
    has not made a United States Sentencing Guidelines ("USSG") § 5K1.1
    motion for a downward departure.
    Finding no reversible error in the district court's
    decisions, we affirm.

    I.
    We   begin   with   an    abbreviated     version   of   the   facts
    underlying this appeal, reserving for our analysis of appellant's
    individual arguments a more detailed description of the facts
    relevant to each.    We present the facts in the light most favorable
    to the verdict.     See United States v. Díaz, 
    670 F.3d 332
    , 337 (1st
    Cir. 2012).
    Appellant was originally indicted with twenty-one other
    defendants for his role in a conspiracy to possess and distribute
    approximately 435 kilograms of oxycodone and 278 kilograms of
    alprazolam from January 2005 to September 2007.                  He moved to
    dismiss the indictment, arguing that there was no single conspiracy
    among the various co-defendants.             The district court denied this
    motion as moot after appellant was re-indicted, in September 2009,
    with just one other co-defendant, Miriam Daisy-Perez.                  This new
    indictment charged that the two co-defendants conspired to possess
    with intent to distribute approximately forty-four kilograms of
    oxycodone   over   the   period      January   2005   to   September   2007.1
    Specifically, appellant allegedly obtained, from a single doctor,
    1
    Oxycodone is an opiate analgesic, available only by
    prescription. As an opiate, it has an effect on users similar to
    that of heroin, and it is often used recreationally. Because of
    these facts, it is classified as a Schedule II controlled substance
    under the Controlled Substances Act and implementing regulations,
    21 C.F.R. § 1308.12(b)(1)(xiii), meaning that it "has a currently
    accepted medical use," but also "a high potential for abuse," 21
    U.S.C. § 812(b)(2)(A) & (B).
    -3-
    at least 2,700 medically unnecessary prescriptions for oxycodone in
    his name and the names of others, and used these prescriptions to
    obtain oxycodone from various pharmacies.
    Appellant was offered a deal by the government, whereby
    it would recommend a sentence of seventy months' incarceration if
    he pled guilty to the charges.         He rejected this offer because of
    the disparity between the deal offered to him and that offered to
    other defendants      involved    in   the same      scheme.2         Accordingly,
    appellant was tried before a jury in June 2010.              Even though he had
    admitted the offense conduct during the government's investigation,
    appellant denied at trial his participation in the conspiracy and
    argued that he was factually innocent.
    The    primary    government     witness   was     Dr.    Jose     Victor
    Vázquez-Senti, from whom appellant obtained the prescriptions used
    in   the   scheme.     Dr.     Vázquez-Senti       testified    that       appellant
    initially came to him as a patient in late 2004, complaining of
    back pain.        However, after the treatment ended, Vázquez-Senti
    continued    to   supply     prescriptions    to    appellant        for   a   fee.
    Initially, appellant simply dictated the names that Vázquez-Senti
    used to write prescriptions.        But, around December 2006, appellant
    provided five "patient" lists to Vázquez-Senti, each containing
    2
    For example, Daisy-Perez was the owner of a pharmacy from
    which oxycodone was obtained.   She negotiated a non-cooperation
    plea agreement calling for a sentence of probation and was
    ultimately sentenced to three years' probation.
    -4-
    between six and fifty-six names and addresses. Appellant regularly
    called   Vázquez-Senti         to     instruct     the    doctor           to   write     new
    prescriptions      in   the    names    of    individuals        on    the      lists,    and
    Vázquez-Senti subsequently delivered the prescriptions to appellant
    -- about twenty each week.               Generally, the prescriptions were
    filled at one of three pharmacies, and, over the course of the
    conspiracy,       Vázquez-Senti        wrote       at    least        2,700        medically
    unnecessary prescriptions for appellant's use.
    The Drug Enforcement Administration ("DEA") became aware
    of the unusual pattern of Vázquez-Senti's prescriptions and started
    an investigation.       The DEA secured a wiretap of the doctor's phone
    and recorded calls in which the doctor and appellant discussed
    their activities, including the preparation of prescriptions and
    how   best   to   obtain      drugs    from    various    pharmacies.               The   DEA
    eventually arrested appellant, Vázquez-Senti, and twenty other
    individuals, including owners of the pharmacies from which drugs
    were obtained and individuals who filled the prescriptions at the
    pharmacies.       Excepting appellant, each of the other individuals
    indicted pled guilty to at least some of the charges against them.
    At the conclusion of a four-day jury trial, appellant was
    found guilty of conspiracy to possess with intent to distribute
    676.50 grams of oxycodone. The jury also found that the government
    was entitled to a forfeiture of $541,200, the estimated proceeds of
    the   conspiracy.          Appellant         was   sentenced          to     240     months'
    -5-
    incarceration, which was below the guidelines range, but the
    maximum sentence permitted by statute.         This appeal followed.
    II.
    A.    Pre-trial and Trial Rulings
    1.   Voir Dire of Potential Jurors
    Appellant challenges two aspects of the district court's
    handling of the voir dire.         He argues that it was error for the
    court to decline to ask potential jurors questions that he proposed
    concerning their legal use of prescription drugs, prior grand jury
    service, and general personality traits.           He also argues that the
    court erred in failing to dismiss juror number 26 for cause because
    of a purported bias against drug users and the fact that she was
    the daughter of two attorneys -- a retired judge and a former
    attorney with the Puerto Rico Department of Justice.
    We review challenges to the trial court's voir dire of
    the jury under an abuse of discretion standard.          United States v.
    Sherman, 
    551 F.3d 45
    , 49 (1st Cir. 2008).             We have noted that,
    "[b]ecause the trial court observes the demeanor and reactions of
    the   prospective   jurors,   we    review   its   determination   of   jury
    impartiality with 'special deference.'"        
    Id. at 51 (quoting
    United
    States v. Moreno Morales, 
    815 F.2d 725
    , 733 (1st Cir. 1987)).
    Furthermore, a court "need not . . . pose every voir dire question
    requested by a litigant.       It is more than enough if the court
    covers the substance of the appropriate areas of concern by framing
    -6-
    its own questions in its own words."                
    Id. (quoting Real v.
    Hogan,
    
    828 F.2d 58
    ,    62   (1st    Cir.   1987))    (internal    quotation        marks
    omitted).
    Here,     although    the    district    court    declined     to   give
    prospective jurors the questionnaire proposed by appellant, it
    noted that many questions included in the questionnaire were
    similar to the questions that it did ask prospective jurors.                       For
    example, it asked about experience with drugs and drug-related
    crimes, whether the prospective jurors had connections to law
    enforcement,         either   themselves     or    through   friends   and    family
    members, and whether the prospective jurors felt that they would be
    able    to    presume      appellant      innocent.      These    questions       were
    sufficient to probe for potential biases.                It was not an abuse of
    discretion for the court to decline to ask the questions proposed
    by appellant.
    The court also did not err in declining to strike juror
    number 26 for cause.          After individual questioning of this juror,
    the court determined that she did not have a bias against drug
    users.       Although the court also noted that the juror's father was
    a retired judge, it determined that this fact did not render her
    unfit for jury service, an unremarkable conclusion.                    As we have
    explained, "[t]here are few aspects of a jury trial where we would
    be less inclined to disturb a trial judge's exercise of discretion,
    absent clear abuse, than in ruling on challenges for cause in the
    -7-
    empaneling of a jury." United States v. Gonzalez-Soberal, 
    109 F.3d 64
    , 69-70 (1st Cir. 1997) (internal quotation marks omitted).
    There was no abuse of discretion here.
    2.   Authentication of Prescriptions by Vázquez-Senti
    Appellant's     challenges     to     his   conviction     include
    preserved     evidentiary    objections,        reviewable   for     abuse   of
    discretion.      United States v. Mare, 
    668 F.3d 35
    , 38 (1st Cir.
    2012).    Of course, even if such an error occurred, it would not
    serve to overturn a conviction if it ultimately proved harmless.
    See United States v. Walker, 
    665 F.3d 212
    , 231-32 (1st Cir. 2011).
    An error is harmless if we can conclude "with fair assurance, after
    pondering all that happened without stripping the erroneous action
    from the whole, that the judgment was not substantially swayed by
    the error."      
    Id. at 231 (quoting
    Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946)) (internal quotation marks omitted).
    The district court admitted into evidence approximately
    2,700    prescriptions    written   by    Vázquez-Senti      and   seized    by
    government agents from computers at the three different pharmacies
    from which appellant obtained drugs.              They were admitted into
    evidence pursuant to Federal Rule of Evidence 901(b)(1), which
    allows authentication through testimony of a witness with knowledge
    of the nature of the item.       The government provided a foundation
    for the prescriptions through testimony by Vázquez-Senti, who
    reported that he wrote them and gave them to appellant and others.
    -8-
    Vázquez-Senti   testified    that   the   prescriptions     were   medically
    unnecessary and that he took the names appearing on them from the
    lists that appellant provided to him.         On appeal, appellant argues
    that it was error for the court to admit the prescriptions without
    authenticating testimony from someone with knowledge of how the
    prescriptions were presented and filled at each pharmacy.
    Rule 901(b)(1) permits authentication of evidence on the
    basis of   "[t]estimony     of a    witness   with    knowledge"   that the
    evidence is what it is claimed to be.         Thus, "[a] document can be
    authenticated [under Rule 901(b)(1)] by a witness who wrote it,
    signed it, used it, or saw others do so."            Orr v. Bank of Am., NT
    & SA, 
    285 F.3d 764
    , 774 n.8 (9th Cir. 2002) (second alteration in
    original) (quoting 31 Charles Alan Wright & Victor J. Gold, Federal
    Practice & Procedure: Evidence § 7106 (2000)) (internal quotation
    marks omitted); see also Dugas v. Coplan, 
    428 F.3d 317
    , 334 n.25
    (1st Cir. 2005) (noting that a letter may be authenticated under
    Rule 901(b)(1) by testimony from its author).
    In this case, Vázquez-Senti testified that he wrote all
    of the prescriptions offered into evidence by the government.
    Having so testified, he could authenticate the prescriptions as
    those written at the request of appellant and testify that they
    were medically unnecessary.         See 
    Orr, 285 F.3d at 774
    n.8.
    Vázquez-Senti testified that he had reviewed the prescriptions,
    -9-
    recognized them as coming from his prescription pad, and identified
    his signature.
    Appellant's argument that the prescriptions were used to
    show how they were presented at various pharmacies -- a topic on
    which   Vázquez-Senti   lacked     knowledge     --     has   no   merit.     The
    government did not have to show how the prescriptions were filled
    to convict appellant of conspiracy.              It was enough to prove
    appellant's role in the conspiracy to show that he obtained the
    prescriptions with the intent that they be used for an illegal
    purpose.    See United States v. Medina-Martinez, 
    396 F.3d 1
    , 5 (1st
    Cir. 2005) ("To prove conspiracy in a criminal case, the government
    must prove beyond a reasonable doubt that an agreement existed to
    commit the underlying substantive offense, and that the defendant
    elected to join the agreement, intending that the underlying
    offense be committed.").       Moreover, the government offered the
    prescriptions to show how appellant obtained the drugs sold through
    the   scheme.    Vázquez-Senti     was     the   only    witness    capable    of
    testifying to the origin of the prescriptions and to the fact that
    they were medically unnecessary. A DEA agent later testified as to
    how   the   prescriptions   were   seized    from     various      pharmacies.
    Accordingly, the court's decision to admit the prescriptions with
    Vázquez-Senti's authentication was not an abuse of its discretion.
    -10-
    3.   Vázquez-Senti's Testimony Regarding Other Defendants
    During his cross-examination, appellant asked Vázquez-
    Senti about benefits he was receiving from the government in
    exchange for his testimony. Vázquez-Senti acknowledged that he was
    held responsible for only 745 medically unnecessary prescriptions,
    and appellant contrasted this number with the 20,000 that Vázquez-
    Senti had    admitted     to    writing.    On   redirect,    the   government
    attempted to diffuse this impeachment by eliciting testimony about
    Vázquez-Senti's     co-defendants,     showing    that   they     had   received
    similar reductions even though they were not testifying.                      Over
    appellant's objection, the district court allowed the government to
    ask Vázquez-Senti if he knew the status of the charges against his
    co-defendants.      After Vázquez-Senti indicated that he did, the
    government asked, "[a]re you aware as to whether or not they pled
    guilty to 435 kilos of oxycodone, or they pled guilty to a lesser
    amount?"    Vázquez-Senti replied, "I believe it were [sic] to a
    lower amounts."      The government briefly alluded to these guilty
    pleas   again    during   its     closing   argument.        In   response     to
    appellant's objection, the court ruled that appellant had opened
    the door on cross-examination to this redirect testimony by asking
    Vázquez-Senti     about   the    benefits   he   received    because     of   his
    cooperation.
    Appellant now repeats his argument that admission of this
    testimony was inappropriate and prejudicial.                In defending the
    -11-
    district court's ruling, the government emphasizes that the cross-
    examination justified questions about the guilty pleas of Vázquez-
    Senti's co-defendants because it referred to the separate criminal
    case in which Vázquez-Senti and his co-defendants were convicted.
    The government argues that it was entitled to show that all of the
    co-defendants, not just Vázquez-Senti, pled guilty to lesser drug
    quantities, and thus Vázquez-Senti did not receive any additional
    benefit because of his testimony against appellant.
    We have previously explained that "where a missing co-
    defendant does not testify, . . . courts and prosecutors generally
    are forbidden from mentioning that a co-defendant has either pled
    guilty or been convicted." United States v. Ofray-Campos, 
    534 F.3d 1
    , 23 (1st Cir. 2008) (internal quotation marks omitted).   This is
    because "[a] defendant is entitled to have the question of his
    guilt determined upon the evidence against him, not on whether a
    codefendant or government witness has been convicted of the same
    charge."   
    Id. at 22-23 (quoting
    United States v. Dworken, 
    855 F.2d 12
    , 30 (1st Cir. 1988)) (internal quotation marks omitted).
    Regardless of whether an absent co-defendant
    has pleaded guilty or been convicted after
    trial, the admission of such evidence not only
    results in the danger that the jury will
    improperly infer guilt by association, it also
    significantly undercuts the defendant's right
    to have a jury's verdict based only upon
    evidence that is presented in open court and
    is thereby subject to scrutiny by the
    defendant.
    -12-
    
    Id. at 23 (internal
        quotation     marks    omitted).        Accordingly,
    "[t]here is no need to advise the jury or its prospective members
    that some one not in court, not on trial, and not to be tried, has
    pleaded guilty.       The prejudice to the remaining parties who are
    charged with complicity in the acts of the self-confessed guilty
    participant is obvious."           
    Id. (internal quotation marks
    omitted).
    In this case, the individuals whose guilty pleas were
    revealed by the government's questioning were not co-defendants of
    appellant, but the co-defendants of Vázquez-Senti.                     However, the
    vast majority of the evidence against appellant concerned the
    relationship      between    the    two    men.      The   guilty     pleas    of   the
    individuals indicted with Vázquez-Senti on charges similar to those
    against appellant are plainly inadmissible.                        The government's
    attempt to suggest this sort of guilt-by-association is clear in
    its reminder to the jury during its closing argument.                   It told the
    jury: "The doctor told you he was indicted with 21 other people,
    including       pharmacists.        So    [appellant]      talks    about     how   the
    prescriptions aren't properly marked.                   You know what?          Those
    responsible for marking the prescriptions have already been dealt
    with."     In light of the fact that the government had elicited
    testimony that Vázquez-Senti's co-defendants had pled guilty, this
    argument was likely to appear as an attempt to suggest to the jury
    that, just as those individuals were held responsible, now it is
    appellant's turn.
    -13-
    Furthermore,        contrary    to     the   government's      argument,
    appellant's questions on cross-examination concerning the benefits
    of Vázquez-Senti's cooperation did not open the door to questions
    about these guilty pleas.            The government seems to take the
    position that any time a defendant explores the benefits that a
    cooperating witness obtained, it is entitled to introduce evidence
    about other participants in the conspiracy and deals that they were
    offered.   However, the government offers no authority for this
    problematic assertion and we find it meritless.                Accordingly, the
    court erred in permitting the government to elicit testimony
    concerning the guilty pleas of Vázquez-Senti's co-defendants.
    That   error,       however,    was     harmless.    The       government
    presented overwhelming evidence of appellant's guilt at trial,
    including: 1) extensive testimony from Vázquez-Senti concerning
    appellant's   role   in    the    scheme     to    obtain   drugs    by    means   of
    medically unnecessary prescriptions, 2) recordings of telephone
    conversations between appellant and Vázquez-Senti concerning the
    sale of prescriptions and the lists of names to be used in writing
    prescriptions, 3) the patient lists provided by appellant to
    Vázquez-Senti, 4) thousands of prescriptions written by Vázquez-
    Senti that he testified were medically unnecessary, 5) testimony
    concerning DEA surveillance of meetings between appellant and
    Vázquez-Senti,    and     6)     testimony        concerning   the    seizure      of
    prescription drugs from two individuals in the company of appellant
    -14-
    immediately after a visit to one of the pharmacies at which the
    medically unnecessary prescriptions were filled.
    The     inappropriate       testimony,    even     coupled    with     the
    government's reference to the guilty pleas in its closing argument,
    is insignificant when considered against the totality of the
    evidence presented at trial.            Thus, we can conclude "with fair
    assurance"    that    the     jury's   decision     was    not    swayed     by   the
    improperly admitted testimony.             
    Walker, 665 F.3d at 231
    .               The
    error, therefore, was harmless. See United States v. Dunbar, 
    553 F.3d 48
    , 59 (1st Cir. 2009) ("The essential inquiry in harmless
    error review is whether the improperly admitted evidence likely
    affected     the    outcome    of    trial."      (internal      quotation    marks
    omitted)).
    4.      Cross-Examination of Vázquez-Senti
    Appellant also argues that it was error for the court to
    refuse to allow him to cross-examine Vázquez-Senti about charges
    that were dismissed as part of the doctor's plea agreement.                       The
    indictment against Vázquez-Senti included one conspiracy count,
    seven distribution counts, and one forfeiture count. Vázquez-Senti
    was permitted to plead guilty to only the conspiracy and forfeiture
    counts. Appellant argues that dismissal of the distribution counts
    was a benefit that he should have been able to use to impeach
    Vázquez-Senti.        He    points   out   that    the    plea   and   cooperation
    agreement entered into by Vázquez-Senti states that the doctor will
    -15-
    not be charged with "any other crimes committed about which the
    defendant has informed the United States." However, when appellant
    attempted to elicit testimony from Vázquez-Senti concerning the
    dismissed charges, the court upheld an objection and blocked this
    line of questioning.
    It    is    well   established    that    "the    right    to   cross-
    examination is not unbridled."          United States v. Rivera-Rodriguez,
    
    617 F.3d 581
    , 591 (1st Cir. 2010) (quoting United States v. Molina,
    
    407 F.3d 511
    , 523 (1st Cir. 2005)).           We have explained that "[s]o
    long as the trial court affords the defendant a fair opportunity
    for     effective      cross-examination,     it     may     impose    reasonable
    restrictions . . . [, and]          [t]he trial court's latitude in shaping
    such restrictions is 'wide.'"            
    Id. (quoting Molina, 407
    F.3d at
    523).    In particular, information concerning pending or dismissed
    charges against a witness may be unfairly prejudicial.                  Where the
    defense    is    permitted     to   cross-examine    a     witness    regarding   a
    cooperation agreement with the government, the details of the other
    charges may not be necessary to establish the potential for bias.
    See United States v. Bunchan, 
    580 F.3d 66
    , 71 (1st Cir. 2009).                 The
    ultimate question is whether "the jury is provided with sufficient
    information concerning formative events to make a discriminating
    appraisal of a witness's motives and bias."                DiBenedetto v. Hall,
    
    272 F.3d 1
    , 10 (1st Cir. 2001) (internal quotation marks omitted).
    -16-
    Here, the jury was provided sufficient information to
    make an informed judgment concerning Vázquez-Senti's motives and
    potential bias.   As noted, Vázquez-Senti acknowledged that he was
    testifying in connection with a plea and cooperation agreement, and
    the agreement was itself admitted into evidence.     It guarantees
    that Vázquez-Senti will not be prosecuted for other crimes about
    which he informs the government, provides that he will be held
    liable for only 745 of the more than 20,000 medically unnecessary
    prescriptions that he wrote, and states that the government will
    recommend a sentence of 108 months' incarceration, well below the
    statutory maximum of twenty years.    In short, there is no doubt
    that the jury was aware of both Vázquez-Senti's incentive to
    testify against appellant and the potential for bias. Accordingly,
    it was not an abuse of discretion for the district court to limit
    cross-examination regarding the dismissed charges.
    5.   Failure to Provide Reports of Investigation
    Appellant argues that the district court erred by failing
    to order the government to provide him two Reports of Investigation
    ("ROI") prepared in connection with interviews of Vázquez-Senti and
    the rough notes taken by investigators during those interviews.
    There were at least three such interviews and three ROIs.       At
    trial, appellant asked the district court to review the ROIs in
    camera and determine if he was entitled to receive them under the
    Jencks Act, 18 U.S.C. § 3500. The district court reviewed the ROIs
    -17-
    and   determined    that    two   of   the    three     did   not      have   the
    characteristics of Jencks material, as they were not verbatim
    records of the interviews and not even prepared on the same days as
    the   interviews   they    documented.       However,    it   did   order      the
    government to turn over the third ROI, which was prepared on the
    day of the interview.      On appeal, appellant asks that we review the
    two ROIs withheld and determine whether they should have been
    turned over pursuant to the Jencks Act.
    The Jencks Act generally requires that any "statement" of
    a   government   witness   relating    to    the subject      matter    of    that
    witness's testimony be turned over to the defendant.                   18 U.S.C.
    § 3500(b).   The Act defines "statement" as:
    (1) a written statement made by said witness
    and signed or otherwise adopted or approved by
    him;
    (2) a stenographic, mechanical, electrical, or
    other recording, or a transcription thereof,
    which is a substantially verbatim recital of
    an oral statement made by said witness and
    recorded contemporaneously with the making of
    such oral statement; or
    (3) a statement, however taken or recorded, or
    a transcription thereof, if any, made by said
    witness to a grand jury.
    
    Id. § 3500(e). We
    have explained that this definition does not
    require that a witness write the statement himself, but that notes
    taken by an investigator during an interview may qualify if read
    back to the witness and adopted.              United States v. Gonzalez-
    Melendez, 
    570 F.3d 1
    , 4 (1st Cir. 2009) (per curiam).                   "Where a
    -18-
    defendant requests discovery of potential Jencks material, our
    precedent requires the district judge to conduct an independent
    investigation of any such materials and determine whether these
    materials are discoverable under the Jencks Act."   
    Id. at 3. This
    independent investigation can take the form of an in camera review
    of the documents or an evidentiary hearing to take testimony from
    the witness who provided the purported "statement." 
    Id. at 3 n.2.
    On appeal, a district court's decision on a Jencks Act claim is
    reviewed for abuse of discretion, United States v. Gonzalez-
    Melendez, 
    594 F.3d 28
    , 35 (1st Cir. 2010), though we review
    underlying legal conclusions de novo and findings of fact for clear
    error, 
    id. In this case,
    the district court conducted the requisite
    investigation, as have we, of the ROIs in question.       Like the
    district court, we do not find the ROIs to be statements within the
    meaning of the Jencks Act. Contrary to appellant's suggestion, the
    ROIs are not substantially verbatim accounts of the interviews with
    Vázquez-Senti, nor do they qualify as "statements" under any other
    provision of the Jencks Act.   18 U.S.C. § 3500(e).   The ROIs are
    short bullet-point summaries of the interviews of Vázquez-Senti,
    and there is no indication that they were ever shown or read to
    Vázquez-Senti, or adopted by him.
    Appellant argues that even if he was not entitled to the
    ROIs, the district court should have also reviewed the rough notes
    -19-
    taken during the interviews with Vázquez-Senti, which served as the
    basis for the ROIs.          At trial, Vázquez-Senti testified that an
    agent took hand-written notes during the interviews, but that this
    note-taking was sporadic and only occurred in connection with
    "some" of his answers.        He also testified that he never saw what
    the agent wrote down and that the agents did not review his answers
    or their notes with him.         Given this testimony, there was plainly
    no opportunity for Vázquez-Senti to adopt the rough notes as his
    own   statements,      nor    could   the     rough    notes   have   been    a
    "substantially       verbatim"    recording    or     transcription   of     the
    interviews.       See 
    id. § 3500(e)(1) &
    (2).         Accordingly, it was not
    an abuse of discretion for the district court to decline to order
    the government to produce these documents to appellant as Jencks
    material.3
    6.    Denial of the Rule 29 Motion
    At the conclusion of his trial, appellant made a motion
    pursuant to Federal Rule of Criminal Procedure 29 for a judgment of
    acquittal.        Although the motion is styled as challenging the
    sufficiency of the evidence supporting his conviction, it actually
    3
    Appellant is correct that the district court identified an
    incorrect legal standard when it stated that appellant would be
    entitled to the ROIs only if "the result of the proceeding would
    have been different if the evidence had been disclosed."        As
    appellant noted, this is an appellate legal standard unrelated to
    the identification of Jencks material. However, for the reasons
    stated, appellant is not entitled to the ROIs under the Jencks Act
    because they do not constitute "statements" within the meaning of
    the Act.
    -20-
    challenges the drug quantity determination made by the jury.4
    According to appellant, this determination was almost entirely
    based on the five lists of names that Vázquez-Senti testified were
    used       to   write    prescriptions,      and    he    argues    that   there   was
    insufficient evidence to link him to the lists.                    In particular, he
    argues that:        1)     the   lists   referred    to    in   recorded telephone
    conversations were different from those introduced as evidence, 2)
    Vázquez-Senti testified that some of the lists appeared to be
    written in the handwriting of an ex-wife of appellant, and 3) there
    was inconsistent evidence concerning the use of the lists because
    Vázquez-Senti           testified   that    the    lists    were    only   used    for
    prescriptions filled at one of the three pharmacies, but many of
    the prescriptions using names from the lists were filled at the
    other two.        Given that these lists were the link tying him to the
    2,700 prescriptions for which he was ultimately held liable,
    appellant argues that the court erred in denying his motion for a
    judgment of acquittal.
    We review a district court's denial of a Rule 29 motion
    de novo, "taking the evidence in the light most favorable to the
    government and making all reasonable inferences in its favor."
    4
    For the purpose of sentencing after a guilty verdict, the
    court will often determine the amount of drugs for which a
    defendant will be held liable. However, it is not unprecedented
    for the jury to be asked to make a specific drug quantity
    determination by means of a special verdict form.      See United
    States v. Casas, 
    356 F.3d 104
    , 127-28 (1st Cir. 2004).
    -21-
    United States v. Giambro, 
    544 F.3d 26
    , 29 (1st Cir. 2008).               Such an
    analysis requires us to "assess whether a reasonable factfinder
    could have      concluded    that   the   defendant     was   guilty    beyond a
    reasonable doubt."        United States v. Fernández-Hernández, 
    652 F.3d 56
    , 67 (1st Cir. 2011).
    We reject appellant's argument.         At best, he identifies
    minor inconsistencies in witness testimony which do not outweigh
    the strong evidence that he did provide the lists to Vázquez-Senti.
    Given that appellant and his ex-wife worked together to obtain
    prescription drugs for some time, the fact that the lists may be in
    his ex-wife's handwriting is consistent with appellant's alleged
    role in the conspiracy and the attribution of drugs obtained using
    prescriptions written in names from those lists to him.
    Furthermore, although Vázquez-Senti testified at one
    point that the lists were used at only one of the pharmacies, later
    that   same    day   he   testified   that   he   did   not   know     where   the
    prescriptions were taken to be filled, allowing for the possibility
    that some of the prescriptions were taken to other pharmacies.
    Additionally, during the course of the investigation, appellant was
    observed with several individuals whose names appeared on the
    lists.   Most importantly, Vázquez-Senti testified that appellant
    provided him the lists and instructed which list to use at a given
    time, and that he gave appellant the prescriptions he wrote using
    the lists.      This testimony was corroborated by the admission of a
    -22-
    recorded phone conversation between appellant and Vázquez-Senti
    discussing the use of these lists.5                In sum, there was ample
    evidence to connect appellant to the patient lists and to support
    use of these lists to determine the drug quantity attributable to
    him.       Therefore, the court was correct to deny appellant's Rule 29
    motion.
    B.   Sentencing Issues
    1.    Drug Equivalency Ratios
    The    district   court    sentenced    appellant   based     on   a
    quantity       of    drugs   determined    by   use    of   equivalency     tables
    established by the sentencing guidelines.                   Appellant argues on
    appeal, as he did below, that the equivalency ratio provided for
    oxycodone is unfairly high and creates unwarranted disparities
    between defendants sentenced for offenses involving oxycodone and
    morphine.            The   sentencing     guidelines    instruct    that,     when
    determining the base level for an offense, one gram of oxycodone is
    equivalent to 6,700 grams of marihuana, and one gram of morphine is
    equivalent to 500 grams of marihuana. USSG § 2D1.1 cmt. n.10(D).
    In an objection to the Presentence Report, appellant argued that
    the court should use the 500-gram equivalency for morphine because
    5
    Appellant points to this conversation as evidence that he
    did not prepare the lists because Vázquez-Senti states during the
    conversation, "Remember that I did list 2, the one that he is
    supposed to get . . . [a]nd the list 3." However, read in context,
    this statement may be understood to mean that Vázquez-Senti had
    recently written prescriptions using lists two and three, not that
    he wrote the lists.
    -23-
    the 6,700-gram equivalency for oxycodone created an unwarranted
    disparity between those convicted of offenses involving the two
    drugs.    In    support,   he   notes   that   oxycodone   is   a   morphine
    derivative and that morphine is more potent and more addictive than
    oxycodone. He further argues that the court committed a procedural
    error by failing to recognize that it had discretion, pursuant to
    Kimbrough v. United States, 
    552 U.S. 85
    (2007), to impose a variant
    sentence based on policy disagreements with the guidelines.             See
    United States v. Stone, 
    575 F.3d 83
    , 89 (1st Cir. 2009) ("[A]fter
    Kimbrough, a district court makes a procedural error when it fails
    to recognize its discretion to vary from the guideline range based
    on a categorical policy disagreement with a guideline.").
    These arguments are without merit.        The court explicitly
    acknowledged its authority to impose a variant sentence based on a
    policy disagreement with the guidelines.        At sentencing, appellant
    invoked Kimbrough and raised what he described as a "fairness
    argument" based on the respective equivalencies for oxycodone and
    morphine. The court agreed that it had discretion under Kimbrough,
    and asked appellant to "[e]xplain to me why this is a fairness
    argument."      In fact, at one point appellant stated, "Let's be
    clear.   You have the authority to disagree [with the guidelines
    equivalency for oxycodone]," to which the court responded, "Of
    course. . . .    But why should I disagree?"     Given this exchange, it
    -24-
    is clear that the court was aware that it had discretion to vary
    from the guidelines range based on a policy disagreement.
    Although our review ends here, it is worth noting that
    the exceptionally high equivalency ratio for oxycodone is the
    product of a 2003 amendment to the guidelines.             See Amendment 657,
    USSG app. C, vol. II at 397 (2003).             As we explained in United
    States v. Ekasala, 
    596 F.3d 74
    (1st Cir. 2010) (per curiam):
    Amendment 657 changed the marijuana equivalent
    for oxycodone in two respects.      First, it
    based the equivalent on the amount of actual
    oxycodone involved rather than on the gross
    weight of the pills containing oxycodone.
    Second, it made 1 gram of oxycodone equivalent
    to 6,700 grams of marijuana, rather than 1
    gram of pill weight equivalent to 500 grams of
    marijuana.
    
    Id. at 75 n.1.
          Thus, unlike for many prescription drugs, when
    determining the guidelines range for an oxycodone-related offense,
    only the weight of the active ingredient (oxycodone) is used, not
    the   full    pill   weight.       This     change   was    made   because   of
    proportionality      issues    arising    when "pills      containing greatly
    differing amounts of actual oxycodone had the same marijuana
    equivalent and, hence, the same base offense level."               
    Id. at 76. In
    contrast, in determining the guidelines range for a
    morphine-related offense, the full weight of the pill or other
    mixture including morphine is used, regardless of potency.                   See
    USSG § 2D1.1(c) n.(A) & cmt. n.1, n.10(D).                   Accordingly, the
    apparent disparity caused by the multipliers used for oxycodone and
    -25-
    morphine is largely neutralized by the use of a larger base weight
    for morphine.      See United States v. Vigil, 
    832 F. Supp. 2d 1304
    ,
    1319, 1327-30 (D.N.M. 2011) (discussing at length the guidelines
    treatment of oxycodone and finding no disparity in treatment of
    oxycodone and morphine).
    2.    Acceptance of Responsibility
    Appellant argues that the court erred in failing to grant
    him a    two-level   reduction    in   offense    level   pursuant   to    USSG
    § 3E1.1(a), which allows such a reduction if "the defendant clearly
    demonstrates acceptance of responsibility for his offense."                
    Id. Appellant argues that
    he fully accepted responsibility for his
    offense, pointing out that he detailed his role in the scheme in a
    series of interviews with authorities and even offered to cooperate
    in the investigation of others.         He asserts that he rejected the
    offered plea agreement only because he felt he was being treated
    unfairly as compared to others convicted in the same scheme, all of
    whom    were    offered   deals   calling   for    a   shorter    period    of
    incarceration.      He argues that insisting on going to trial under
    these circumstances is not incompatible with the type of acceptance
    of responsibility called for by USSG § 3E1.1(a).
    A sentencing court's determination of whether a defendant
    accepted responsibility is reviewed for clear error. United States
    v. Garrasteguy, 
    559 F.3d 34
    , 38 (1st Cir. 2009).                 In order to
    qualify for a reduction pursuant to USSG § 3E1.1(a), "a defendant
    -26-
    must truthfully admit or not falsely deny the conduct comprising
    the conviction, as well as any additional relevant conduct for
    which he is accountable." 
    Garrasteguy, 559 F.3d at 38
    . Given this
    requirement,     "defendants   who    proceed    to   trial   and    put   the
    government to its proof normally do not qualify for any reduction
    for acceptance of responsibility . . . [, and] proceeding to trial
    creates a rebuttable presumption that no credit is available." 
    Id. at 38-39 (citations
    omitted). However, the guidelines provide that
    in "rare situations" the reduction may be available to those who go
    to trial. USSG § 3E1.1 cmt. n.2.       Such circumstances include, "for
    example, where a defendant goes to trial to assert and preserve
    issues that do not relate to factual guilt (e.g., to make a
    constitutional    challenge to a       statute   or a    challenge    to   the
    applicability of a statute to his conduct)."            
    Id. This case does
    not present one of the "rare situations"
    in which going to trial is compatible with a § 3E1.1(a) reduction.
    While it is true that appellant initially acknowledged his conduct
    to investigators, he did not do so at trial.          His defense at trial
    was not based on issues other than his factual guilt; rather, he
    disputed every aspect of the government's case and denied his role
    in the conspiracy.    Given this conduct, his reasons for rejecting
    the government's offered plea agreement are immaterial, and the
    court did not err in deciding that his decision to go to trial and
    deny his factual guilt disqualified him from receiving a § 3E1.1(a)
    -27-
    reduction.   See United States v. González-Vélez, 
    587 F.3d 494
    , 509
    (1st Cir. 2009) (stating that "the failure of plea negotiations is
    generally not . . . a circumstance" permitting a § 3E1.1(a)
    reduction for a defendant who chooses to go to trial).
    3.   Consideration of § 3553(a) Factors
    Although appellant's final argument occasionally seems to
    be a claim that the 240-month sentence imposed was substantively
    unreasonable, this claim is not actually raised.         Rather, he
    focuses on two claims of procedural error.6   First, he argues that
    the court erred in determining that it could not consider the
    extent of his cooperation with the government as a basis for a
    downward variance in the absence of a USSG § 5K1.1 substantial
    assistance motion from the government. Second, he asserts that the
    court erred in failing to explain why it rejected an argument for
    a lower sentence based on the disparity between the sentences
    imposed on him and others convicted as part of the same scheme.
    See United States v. Dávila-González, 
    595 F.3d 42
    , 47 (1st Cir.
    2010) (noting that procedural error includes "failing to consider
    6
    We draw a distinction between claims of procedural error in
    sentencing, such as "failing to calculate (or improperly
    calculating) the Guidelines range, treating the Guidelines as
    mandatory, failing to consider the § 3553(a) factors, selecting a
    sentence based on clearly erroneous facts, or failing to adequately
    explain the chosen sentence," United States v. Martin, 
    520 F.3d 87
    ,
    92 (1st Cir. 2008) (quoting Gall v. United States, 
    552 U.S. 38
    , 51
    (2007)), and claims of substantive unreasonableness, which
    challenge the reasonableness of the sentence imposed given "the
    totality of the circumstances," 
    id. -28- the 18
    U.S.C. § 3553(a) factors" or "failing to adequately explain
    the chosen sentence").
    With regard to appellant's first argument, § 3553(a)(1)
    instructs   a     sentencing    court      to   consider   the     "history      and
    characteristics of the defendant," without limitation.                     As the
    Second Circuit has explained, "[t]his sweeping provision presumably
    includes    the     history     of     a     defendant's       cooperation       and
    characteristics     evidenced    by     cooperation."          United   States    v.
    Fernandez, 
    443 F.3d 19
    , 33 (2d Cir. 2006). Furthermore, nothing in
    the guidelines suggests that a court's discretion to consider all
    of a defendant's relevant conduct under § 3553(a) is constrained by
    the   government's    decision       not   to   file   a   §    5K1.1   motion.
    Accordingly, we join our sister circuits in sensibly holding that,
    in determining the appropriate sentence within the guidelines, or
    in varying from the guidelines, a sentencing court has discretion
    to consider the defendant's cooperation with the government as a
    § 3553(a) factor, even if the government has not made a USSG
    § 5K1.1 motion for a downward departure.               See United States v.
    Massey, 
    663 F.3d 852
    , 858 (6th Cir. 2011); United States v.
    Leiskunas, 
    656 F.3d 732
    , 737 (7th Cir. 2011); 
    Fernandez, 443 F.3d at 33
    ; United States v. Doe, 
    398 F.3d 1254
    , 1260-61 (10th Cir.
    2005); Hutchison, et al., Federal Sentencing Law and Practice §
    5K1.1, cmt. 2 n.3 (2012) (noting that although a court may not
    grant a downward departure for substantial assistance without a
    -29-
    motion from the government, "[p]ost-Booker . . . sentencing courts
    may weigh a defendant's assistance or attempts to assist the
    government as part of the § 3553(a) analysis and vary from the
    Guidelines if appropriate").       No circuit court has held to the
    contrary.
    However, although appellant's legal argument is correct,
    we detect no error in the district court's assessment of the
    § 3553(a) factors.     It is true that, during appellant's sentencing
    hearing, the court initially expressed doubt that it could grant a
    downward variance based on his cooperation absent a motion pursuant
    to USSG § 5K1.1.     But the court offered appellant the opportunity
    to "convince me otherwise."     After appellant identified cases from
    other circuits holding that a sentencing court has such discretion,
    the court stated, "I understand your argument.          Thank you."    It
    went on to hear extensive argument from appellant concerning his
    cooperation with the government, and also asked the government to
    address the issue of his cooperation on the merits.        Accordingly,
    the record indicates that the court understood that it had the
    discretion to consider the extent of appellant's cooperation in
    fashioning the appropriate sentence.
    Appellant's argument concerning the alleged failure of
    the district court to explain its rejection of his sentencing
    disparity   argument    also   fails.    At   the   sentencing   hearing,
    appellant had ample opportunity to elaborate on the disparity
    -30-
    argument, which had already been raised in his objections to the
    Presentence Report, and he did so.               The gist of this argument was
    that the others who pled guilty as part of the scheme in which he
    was involved received far lower sentences.                  While that is so,
    appellant ignores important differences between his circumstances
    and those of the other individuals he identifies.                 Appellant was
    considered a leader in the conspiracy and had a more extensive
    criminal history than some of the other participants.                  Given that
    "a sentencing court is not required to address frontally every
    argument advanced by the parties, nor need it dissect every factor
    made relevant by 18 U.S.C. § 3553,"                United States v. Turbides-
    Leonardo, 
    468 F.3d 34
    , 40-41 (1st Cir. 2006), the court did not err
    by   failing    to     explain    why    it   rejected   appellant's    disparity
    argument,      especially        where   that    argument   was   so    obviously
    meritless.
    IV.
    For the foregoing reasons, we find appellant's arguments
    without merit.         Although the district court did err in admitting
    testimony      about    the   guilty     pleas    of   appellant's     former   co-
    defendants, that error was harmless.              Accordingly, the judgment is
    affirmed.
    So ordered.
