    BARRON, Circuit Judge.            Gustavo Castro-Caicedo appeals
    his conviction and sentence for participating in a conspiracy that
    sought to send cocaine from Colombia to the United States.                          His
    primary objection is that federal agents used a highly suggestive
    means to prompt a member of the conspiracy to identify him as a
    confederate,      and   thus     that    the    government's          use    of     the
    identification at trial violated his constitutional right to due
    process.    Castro-Caicedo also challenges the admission of other
    testimony under the Federal Rules of Evidence.                     And, finally, he
    argues that his sentence was unreasonably lengthy. But although the
    record shows the District Court was justified in finding that the
    means used to obtain the identification were problematic, we find
    the record also supports the District Court's well-considered
    judgment that there was reason enough to credit the identification
    to permit a jury to decide its worth.             Because we see no merit in
    Castro-Caicedo's remaining challenges -- each of which he raises for
    the first time on appeal -- we affirm both the conviction and the
    sentence.
    I.
    Following    an     investigation        by   a    Drug       Enforcement
    Administration      (DEA)      task   force    and   cooperating       elements      of
    Colombian law enforcement agencies, Castro-Caicedo, a Colombian
    national,   was     indicted     in     Massachusetts         on    one     count   of
    participating in a conspiracy to import cocaine to the United
    -2-
    States, or to manufacture and distribute cocaine for importation to
    the United States.           
    21 U.S.C. §§ 952
    (a), 959(a), 960(b)(1)(B).                  At
    trial,      the    conspiracy's          leader   testified   that    the       conspiracy
    involved, in part, transporting tens of kilograms of cocaine from
    Cali,       a    city   in   Colombia,       to     the   Colombian      port    city    of
    Buenaventura, from where it would be sent by ship to the Bahamas.
    The government also put forth evidence to show Castro-Caicedo helped
    organize some of those shipments out of Buenaventura from at least
    2007 to 2009.
    To prove the further allegation that the conspiracy
    sought      to    ensure     the       cocaine    would   reach   this    country,      the
    government        presented        a    variety    of   evidence,   both    direct      and
    circumstantial. Castro-Caicedo's challenge to his conviction takes
    aim at only certain portions of this evidence, and we tailor our
    recitation of the facts accordingly.
    Castro-Caicedo's lead challenge is to one piece of direct
    evidence: the testimony of an informant we will call "J.D."1                            J.D.
    used to be a seaman on a container ship based out of Freeport,
    Bahamas that often called at Buenaventura, Colombia. Federal agents
    first spoke with J.D. about his participation in a cocaine smuggling
    operation in 2009.            In 2012, a little more than a month before
    1
    We assign these initials to identify the informant "in
    light of concerns about the safety of cooperating witnesses raised
    by the Committee on Court Administration and Case Management of the
    Judicial Conference of the United States."       United States v.
    Etienne, ___ F.3d ___, 
    2014 WL 5462541
    , at *1 n.1 (1st Cir. 2014).
    -3-
    trial, J.D. first told the agents that more than four years before
    he met twice with a person known to him then only as the owner of
    a home in the city of Buenaventura.         J.D. told the agents that,
    through those two meetings, he and the owner of that house reached
    an agreement to ship certain quantities of cocaine to the United
    States.
    Federal agents then showed J.D. eleven photographs, three
    of which depicted other members of the conspiracy and the last of
    which was an image of Castro-Caicedo.         Upon seeing that picture,
    J.D. identified it as depicting the owner of the house and thus the
    person with whom he had struck the deal.
    Castro-Caicedo moved to suppress the identification prior
    to   trial.      He   argued   the   presentation   of   the   photographs
    impermissibly cued J.D. to pick out Castro-Caicedo's picture.          And
    he further argued that, by then, too much time had passed since
    J.D.'s last encounter with the person he purported to identify for
    the identification to be reliable enough to overcome the taint of
    that impermissibly suggestive display of photographs.             He thus
    argued the use of the identification at trial would violate his
    constitutional right to due process.
    The District Court disagreed.    It found the photographs
    had been assembled in a manner that was unduly suggestive.         But the
    District Court also found the identification was still reliable
    enough to put to the jury.
    -4-
    Castro-Caicedo         did    not   raise   his   other   evidentiary
    challenges at trial.         He thus presses them for the first time on
    appeal.
    The   first     of    these    unpreserved    objections    concerns
    testimony about two large seizures of cocaine shipments in Colombia
    in 2008, one of 875 kilograms of cocaine and the other of 500
    kilograms.    The government introduced the testimony to support its
    contention there was a cocaine conspiracy to join, that coded
    conversations      between        conspirators     (including    Castro-Caicedo)
    referred to cocaine trafficking, and that the conspiracy was of such
    scope that it must have aimed to send cocaine to the United States.
    Castro-Caicedo contends he had no direct tie to either
    shipment, and the government concedes the point.                  Castro-Caicedo
    thus argues that, under the Federal Rules of Evidence, the testimony
    was either irrelevant or unduly prejudicial and that his conviction
    should be reversed in consequence.
    Castro-Caicedo's other unpreserved evidentiary objection
    concerns a Colombian police officer's testimony about a polygraph
    test he took upon joining the DEA task force.                     In addition to
    testifying about a recorded call mentioning the 500-kilogram seizure
    discussed above, this officer also testified about a number of other
    recorded calls involving Castro-Caicedo and others who pled guilty
    to involvement in the conspiracy.                 Castro-Caicedo contends the
    officer's testimony about the polygraph led jurors to give undue
    -5-
    weight to his credibility. Castro-Caicedo thus argues the admission
    of this polygraph testimony violated the Federal Rules of Evidence
    and requires reversal of the conviction.
    Finally, Castro-Caicedo challenges his sentence.    Here,
    too, he presses an argument he makes for the first time to us.
    Castro-Caicedo contends the 300-month prison    sentence he received
    is unreasonable.    He argues the District Court unjustifiably varied
    upward from the sentence suggested by the Sentencing Guidelines and,
    in doing so, imposed a sentence that far surpasses the length of the
    sentences given to other members of the conspiracy, including its
    purported leader.
    We use this same order of presentation to address the
    merits of each challenge.
    II.
    J.D.'s identification purported to offer direct evidence
    that Castro-Caicedo participated in the cocaine conspiracy and that
    the conspiracy intended to send cocaine to the United States --
    evidence, in other words, that directly supported the conspiracy
    charge set forth in the indictment.     Typically, juries weigh the
    reliability of evidence, including eyewitness identifications. But
    when the government uses highly suggestive means to elicit an
    eyewitness identification, there may be reason to depart from that
    norm.
    -6-
    In     such    a   case,   there       is   a   real    concern    the
    identification will be mistaken, or at least will result from the
    suggestive means the government used to prompt the witness rather
    than from the witness's memory of having encountered the person
    identified.          And the Supreme Court has made clear that very concern
    may arise if "the police display to the witness only the picture of
    a single individual who generally resembles the person he saw, or
    if they show him the pictures of several persons among which the
    photograph of a single such individual recurs or is in some way
    emphasized."          Simmons v. United States, 
    390 U.S. 377
    , 383 (1968).
    Because, in such circumstance, the government's own
    choice     to        use   a    suggestive       prompt     casts   doubt    on    the
    identification's           reliability,        the   Constitution      may   bar   the
    government from benefitting from the problematic means used to
    elicit that information.            Perry v. New Hampshire, 
    132 S. Ct. 716
    ,
    726 (2012).          Thus, upon a defendant's showing the government used
    unduly suggestive means to obtain an eyewitness identification, the
    government must show why the identification should be put to the
    jury despite its tainted origins.                Neil v. Biggers, 
    409 U.S. 188
    ,
    199 (1972); United States v. Jones, 
    689 F.3d 12
    , 17 (1st Cir. 2012).
    In assessing a district court's ruling on such questions,
    we review the findings of fact for clear error and the conclusions
    of   law   de    novo,        allowing   for    some   "reasonable     latitude    for
    case-specific decisions" applying law to fact.                  Jones, 689 F.3d at
    -7-
    18.   Applying that standard, we conclude the District Court did not
    err   in    finding     that,   although    the   government   presented     the
    photographs in an unduly suggestive way, the government had met its
    burden of showing the jury should still be allowed to consider
    J.D.'s identification.
    A.
    We start with what the record shows about what led the
    federal agents to show J.D. the photographs in the first place.               In
    April      of   2009,   federal   agents    convinced   J.D.   to   become    a
    confidential informant.         In that role, J.D. told the agents about
    cocaine shipments from Colombia to the Bahamas.
    An agent testified that J.D. did not at that time
    specifically mention having met with an owner of a house in
    Buenaventura, that such a person was involved in those cocaine
    shipments, or that this person reached an agreement with J.D. to
    send cocaine to the United States.          But during a follow-up meeting
    with a federal prosecutor and investigator in August 2012, the
    agents testified, J.D. did for the first time specifically mention
    meeting such a person, that person's involvement with the shipments,
    and the deal they reached.
    And while J.D. did not at that time provide the name of
    this person, he did offer a description of him.            Testimony showed
    J.D. described him as being between five feet eight inches and five
    feet ten inches tall, about fifty years old, and having a dark
    -8-
    complexion, a "sagging . . . belly," a limp, and limited English
    facility.
    The prosecutor and investigator then,     impromptu, showed
    J.D. a number of photographs on the prosecutor's laptop.              J.D.
    testified he initially told the prosecutor and investigator he would
    not be able to identify the person with whom he had met.              The
    investigator, by contrast, testified J.D. said he might be able to
    recognize some individuals from the conspiracy.
    The   investigator   prefaced   the   presentation   of    the
    photographs by telling J.D. he might not recognize anyone in the
    photographs, he need not identify any specific photograph or person,
    and he should identify someone appearing in one of the photographs
    only if he was certain he knew who was depicted.         J.D. saw each
    photograph sequentially, and he did not know at the outset how many
    he would see by the end.
    The prosecutor and investigator ultimately showed J.D.
    eleven photographs.    The set included a picture of Castro-Caicedo
    at the end, preceded by ten photos of other men, including three
    members of the conspiracy.
    The District Court found this presentation concerning,
    explaining that it was not "of a conventional sort" and that "[i]t
    wasn't assembled to meet the standards of a typical photo array."
    The District Court found especially troubling that there were "not
    a number of people of Mr. Castro-Caicedo's age or appearance" and
    -9-
    that "4 of the 11 are people who have been charged in this case and
    three of whom have pled guilty." And it ruled, in the end, that the
    display was "impermissibly suggestive."
    Whether or not the inclusion of the conspirators was
    itself problematic, cf. United States v. Hilario-Hilario, 
    529 F.3d 65
    , 71 (1st Cir. 2008) (assuming but not deciding that a photo
    lineup that grouped conspirators together was unduly suggestive),
    the record supports the District Court's conclusion that there were
    not "a number of people of Mr. Castro-Caicedo's age or appearance."
    The photograph of Castro-Caicedo appears to depict a person far
    older and with darker skin than any other person in the set.   He is
    also the only person in the set whose sagging belly is shown.
    Moreover, Castro-Caicedo is depicted in a striking yellow and blue
    striped shirt while the others wore more muted garb.
    The assembly of photographs thus raises the concern that
    its design cued J.D. to pick out that photograph in particular. See
    United States v. DeCologero, 
    530 F.3d 36
    , 62 (1st Cir. 2008) (noting
    that undue suggestion depends on "whether the photo array included,
    as far as was practicable, a reasonable number of persons similar
    in appearance to the suspect"); United States v. Lau, 
    828 F.2d 871
    ,
    876 (1st Cir. 1987) (characterizing Simmons, 
    390 U.S. at 383-84
    , as
    holding that "police should avoid emphasizing picture of suspect in
    photographic identification").     And thus the District Court was
    justified in finding the photographs had been shown to J.D. in a
    -10-
    manner so suggestive it gave rise to the risk of an unreliable
    identification.      See Simmons, 
    390 U.S. at 383
     (The danger of an
    incorrect identification "will be increased if the police display
    to the witness only the picture of a single individual who generally
    resembles the person he saw, or if they show him the pictures of
    several   persons    among     which   the    photograph       of   a    single   such
    individual recurs or is in some way emphasized.").
    B.
    Nonetheless, the District Court went on to rule the
    identification    was   sufficiently         reliable    to    permit     a   jury   to
    consider it.     And because the record supports that judgment, too,
    we decline to disturb it.
    The      District    Court    reached        this    conclusion        after
    considering the five factors that much precedent makes relevant to
    an overall determination about the reliability of an identification
    that has been prompted by unduly suggestive means.                      Those factors
    are:
    [T]he opportunity of the witness to view the
    criminal at the time of the crime, the
    witness' degree of attention, the accuracy of
    the witness' prior description of the
    criminal, the level of certainty demonstrated
    by the witness at the confrontation, and the
    length of time between the crime and the
    confrontation.
    Biggers, 
    409 U.S. at 199-200
    .
    As to the first factor, the record supports the District
    Court's finding that J.D. "had a good opportunity to view" Castro-
    -11-
    Caicedo over "about" an hour and a half in direct conversation in
    close quarters.     J.D. testified his container ship twice docked in
    Buenaventura in late 2007 and early 2008.      He further testified he
    met each time with the man he purported to identify in close
    proximity in the man's house, for "[p]robably less than an hour" in
    the first meeting and "less than thirty minutes" in the second.
    That is a total period of time we have previously described as
    providing "ample time to view the defendant," United States v.
    Flores-Rivera, 
    56 F.3d 319
    , 330 (1st Cir. 1995), and a period
    exceeding the half hour Biggers thought a "considerable period of
    time," 
    409 U.S. at 200
    .
    J.D.'s testimony also supports the District Court's
    conclusion    on   the   second   factor:   J.D.   was   "paying   careful
    attention" to Castro-Caicedo during these meetings.         Not only did
    J.D. testify to that very fact, but his testimony about the context
    of those meetings supports it:       J.D. testified he was meeting with
    coconspirators to forge a deal about a drug shipment.         See United
    States v. Drougas, 
    748 F.2d 8
    , 27-28 (1st Cir. 1984) (concluding
    that cooperating witness in drug smuggling operation had incentive
    and opportunity to pay close attention to coconspirator who was also
    a state trooper).
    Castro-Caicedo speculates J.D. may have been drunk during
    the first meeting because J.D. testified the owner offered him a
    beer.   But J.D. never testified he took the offer or consumed any
    -12-
    alcohol.   Indeed, J.D. testified he countered by asking for coffee.
    Nothing in the record thus would compel an inference J.D. was
    intoxicated and could not have paid the close attention the District
    Court found. Castro-Caicedo also asserts J.D. was distracted during
    the second meeting because J.D. testified he was using the internet
    at the outset of the meeting while others fetched cocaine.    But the
    District Court found J.D. was paying close attention during both
    meetings, and the fact that J.D. used the internet before his
    discussions with the owner in the second meeting does not render
    that finding clearly erroneous.
    The District Court found that the third factor favored
    the use of the identification, as J.D.'s prior description was
    "quite consistent" with Castro-Caicedo's actual characteristics.
    That prior description was not so precise or unusual to make it
    proper for the government to present photographs containing only one
    matching it.   Compare DeCologero, 
    530 F.3d at 62
     ("[The defendant]
    has no unusual features that might complicate the search for others
    with similar appearances, yet the other photos in the array were not
    of men who looked similar to [him] . . . ."), with United States v.
    Holliday, 
    457 F.3d 121
    , 126 (1st Cir. 2006) ("[T]he defendant's
    appearance was so unusual that '[i]t would be unreasonable to expect
    the police to find pictures of eight other men who not only shared
    his age, weight, hairstyle, and ethnicity, but in addition had a
    similar    pattern   of   facial   discoloration.'"   (alteration   in
    -13-
    original)).       And    the    correlation       between    a   witness's        prior
    description and the accuracy of that witness's later identification
    may be weaker than commonly thought and might sometimes be negative.
    See Massachusetts Supreme Judicial Court Study Group on Eyewitness
    Evidence, Report and Recommendation to the Justices 65 (2013).                      But
    given the high degree of attention and substantial opportunity to
    observe that the District Court found the witness had here, the
    "case-specific" judgment the District Court made on this factor
    merits "reasonable latitude," Jones, 689 F.3d at 18, and is not
    clearly wrong.
    The record does not clearly support the District Court's
    finding that the fourth factor -- the eyewitness's certainty -- also
    favored the use of the identification. For while the District Court
    found J.D. was "quickly certain" in identifying Castro-Caicedo, the
    record    supports      the    judgment    J.D.     was     quick    to    make    the
    identification, but not necessarily that he expressed any view as
    to his level of certainty.            But the lack of clarity on that point
    matters little.      J.D.'s certainty is at best a neutral factor, and
    here there is no indication of J.D.'s lack of certainty. See Jones,
    689 F.3d at 18 ("[T]he witness' lack of confidence is certainly a
    reliable warning sign, while the presence of confidence is probably
    closer to a neutral factor.").
    And   finally,      the    record   comports      with   the    District
    Court's   finding    about     the    relatively     limited     import     in    this
    -14-
    particular case of the fifth factor, concerning the lapse of time
    prior to the identification.           That lapse was lengthy -- four and a
    half years.      But while we have said "a five-year gap between the
    crime and the photographic identification is very much greater than
    would ordinarily be permissible to find an . . . identification
    reliable,"      Drougas, 
    748 F.2d at 28
    ; see also Biggers, 
    409 U.S. at 201
        ("[A]    lapse    of    seven   months   between         the   rape    and    the
    confrontation . . . would be a seriously negative factor in most
    cases."), we have permitted an identification to go before the jury
    where the identification came "nearly seven years" after the witness
    observation when "the other reliability criteria were sufficiently
    persuasive," Flores-Rivera, 
    56 F.3d at 331
    .               In particular, we have
    upheld a district court's denial of a motion to suppress where the
    witness had "between one and two hours" to observe the suspect and
    had special reason to pay close attention.                
    Id. at 330-31
    ; see also
    Drougas, 
    748 F.2d at 28
     (holding that a five-year gap was outweighed
    by a coconspirator identification that was based on "considerable"
    opportunity to observe).          We find no reason to reach a different
    result here, given the District Court's findings, supported by the
    record, regarding the circumstances of the substantial contacts
    between J.D. and the person he later identified as Castro-Caicedo.
    On appeal, Castro-Caicedo does raise for the first time
    an    additional   set    of    arguments     for   why    we    should      doubt   the
    identification -- namely, that recent social science research
    -15-
    reveals the perils of crediting an eyewitness's memory.                         The
    Innocence Project, as amicus, agrees.
    But Castro-Caicedo did not raise these arguments below.
    If he had, the District Court could have weighed them in deciding
    Castro-Caicedo's motion to suppress -- assuming the District Court
    did not implicitly do so on its own. Castro-Caicedo also could have
    presented   the    same    arguments    to    the    jury   or   asked    for   jury
    instructions      noting   those   possible         concerns     with    eyewitness
    identifications.       See Jones, 689 F.3d at 20 (permitting jury
    instructions).     But Castro-Caicedo took advantage of none of these
    opportunities to make his case.          And the general survey of social
    science research he now presents for the first time on appeal offers
    us no reason to reject the specific and detailed findings made below
    about the distinguishing features, and hence reliability, of this
    particular identification.
    III.
    Castro-Caicedo also complains the District Court admitted
    testimony regarding two seizures of cocaine to which he had no
    direct tie -- and the government concedes there was no such direct
    link.   Castro-Caicedo thus argues the testimony was irrelevant or
    substantially more prejudicial than probative and should not have
    been admitted.     Fed. R. Evid. 401, 402, 403.
    But even when evidentiary challenges of this sort are
    preserved, we are disinclined to find a District Court has abused
    -16-
    its discretion in assessing the relevance or unduly prejudicial
    nature of testimony. United States v. Lyons, 
    740 F.3d 702
    , 718 (1st
    Cir. 2014).     We are even less willing to do so when, as here, the
    defendant failed to object below, and we may then reverse only if
    the error is plain.       United States v. Burdulis, 
    753 F.3d 255
    , 263
    (1st Cir. 2014) (We "requir[e] the appellant to show that the error,
    if any, was 'clear or obvious,' 'affected his substantial rights,'
    and   'seriously      impaired    the     fairness,     integrity,     or   public
    reputation of judicial proceedings.'" (quoting United States v.
    Mardirosian, 
    602 F.3d 1
    , 11 (1st Cir. 2010))).
    Here, the challenged testimony about one of the seizures
    -- consisting of 875 kilograms of cocaine, of which the leader of
    the   conspiracy     allegedly    owned       60   kilograms   --   furthered    the
    government's contention that there was a conspiracy to ship cocaine
    that Castro-Caicedo could have joined. That testimony also provided
    context for decoding the recorded conversations between the alleged
    leader   of    the   conspiracy   and     a    coconspirator    discussing      that
    seizure.      And, by doing so, the testimony aided the government in
    its effort to show that coded conversations involving Castro-Caicedo
    and others were, indeed, about cocaine trafficking.                 Finally, this
    testimony, by showing the large quantity of drugs dealt in by the
    conspiracy's leader, linked to the government's contention that the
    goal of the conspiracy was to send cocaine to the United States, as
    -17-
    other testimony suggested about two-thirds of South American cocaine
    goes there.
    The challenged testimony about the other seizure --
    consisting of 500 kilograms of cocaine -- indicated one of the
    coconspirators thought the DEA had seized the cocaine.      (It was
    actually seized by a Colombian law enforcement agency.)   Thus, this
    testimony assisted the government in advancing its theory that the
    conspirators intended to reach the U.S. market.
    As precedent supports the relevance of this kind of
    evidence, see United States v. Díaz-Arias, 
    717 F.3d 1
    , 20-22 (1st
    Cir. 2013), and the District Court properly instructed the jury that
    Castro-Caicedo could be convicted only for his own state of mind and
    behavior, not for those of another, no further description of the
    challenged testimony's value is necessary to insulate it from
    Castro-Caicedo's late-breaking claims about lack of relevance and
    undue prejudice.2
    IV.
    Castro-Caicedo also challenges testimony from a Colombian
    police officer about a polygraph test he took to join the DEA task
    force. In his testimony, the officer stated the polygraph was given
    2
    Castro-Caicedo also argues on appeal that these shipments
    are irrelevant and unduly prejudicial for the further reason they
    actually were part of an entirely separate conspiracy for which he
    was not charged. But Castro-Caicedo has not carried his burden on
    plain error review of showing that the shipments were obviously
    part of a separate conspiracy, and thus we need not consider how
    his argument would fare if he had made such a showing.
    -18-
    "to make sure that the people working with the specialized group are
    the best possible on the team."              That officer then went on to
    testify   about    a    large   seizure      of    cocaine    belonging   to   a
    coconspirator and phone calls between Castro-Caicedo and other
    coconspirators.
    On appeal, Castro-Caicedo concedes he did not object to
    this testimony below.       But he argues allowing it was plain error.
    He   references   the   concern    we   have      expressed   about   polygraph
    evidence, see United States v. Mare, 
    668 F.3d 35
    , 42 (1st Cir. 2012)
    ("This is the latest in a growing line of cases that ought to
    suggest, if not a per se rule, then at least a code of best practice
    for the virtuous prosecutor: polygraph evidence, even that dealing
    with matters other than the actual results of an examination, is
    usually   more    trouble   than   it   is    worth.");      United   States   v.
    Rodríguez-Berríos, 
    573 F.3d 55
    , 73 (1st Cir. 2009) (observing that
    "[p]olygraph results are rarely admissible at trial" due to concerns
    about their reliability and prejudicial effect), and he relies on
    precedent from another circuit that raises the particular concern
    that such testimony may constitute improper vouching or bolstering
    of a witness's credibility.        See United States v. Ross, 
    703 F.3d 856
    , 875-76 (6th Cir. 2012).
    The officer, however, made reference to the polygraph
    test only in passing, and the government did not bring it up again
    during testimony or in closing arguments.            Castro-Caicedo has thus
    -19-
    not met the high burden required to show the testimony caused the
    prejudice necessary to warrant reversal on plain error review,
    especially considering the government's other evidence, including
    J.D.'s identification. See United States v. Rodriguez, 
    525 F.3d 85
    ,
    96 (1st Cir. 2008) ("The determination of whether [erroneously
    admitted] testimony was harmful [under the plain error test] demands
    a panoramic, case-specific inquiry considering, among other things,
    the   centrality   of   the   tainted    material,   its   uniqueness,   its
    prejudicial impact, the uses to which it was put during the trial,
    the relative strengths of the parties' cases, and any telltales that
    furnish clues to the likelihood that the error affected the fact-
    finder's resolution of a material issue." (internal quotation marks
    omitted)).
    V.
    Finally, Castro-Caicedo objects that his 300-month prison
    sentence is unreasonable because it unjustifiably varies upward from
    the guideline (and statutory mandatory minimum) sentence of 240
    months, and the far-shorter sentences of his coconspirators.3             We
    normally review substantive reasonableness challenges for an abuse
    3
    Castro-Caicedo also objects that his 300-month prison
    sentence unreasonably deviated from the range of 168 to 210 months
    that would have applied under the Sentencing Guidelines but for the
    statutory mandatory minimum.    But he does not dispute that the
    minimum applied because of his prior conviction for a felony drug
    offense. 
    21 U.S.C. §§ 851
    , 960(b)(1). And because the 240-month
    minimum exceeded the otherwise-applicable guideline range, the 240-
    month minimum became the guideline sentence. U.S.S.G. § 5G1.1(b).
    -20-
    of discretion. United States v. Politano, 
    522 F.3d 69
    , 72 (1st Cir.
    2008).    But because Castro-Caicedo failed to raise these objections
    in the court below, we review them only for plain error.                     United
    States v. Tavares, 
    705 F.3d 4
    , 33 (1st Cir. 2013).
    When deviating from the Guidelines sentencing range, a
    sentencing judge must give reasons "rooted either in the nature and
    circumstances of the offense or the characteristics of the offender.
    In such a situation, the factors deemed relevant by the sentencing
    court must add up to a plausible rationale for the sentence imposed
    and must justify a variance of the magnitude in question."                   United
    States    v.   Flores-Machicote,     
    706 F.3d 16
    ,   21   (1st   Cir.    2013)
    (internal quotation marks and citations omitted).                 And here the
    District Court did offer such reasons and supply such a rationale.
    The District Court concluded Castro-Caicedo's offense was
    "very serious" because his business was sending "large quantities"
    of cocaine from Colombia to the United States, with "devastating
    effect[s] on individuals, on families, on neighborhoods, on cities,
    states, and all of the United States."             See 
    18 U.S.C. § 3553
    (a)(1),
    (a)(2)(A).        The   District   Court    also    concluded    Castro-Caicedo
    required an upward variance to deter him from future criminal acts
    and to protect the public, due to his several prior convictions for
    serious offenses and his failure to accept any responsibility during
    allocution for his present or past crimes. See 
    id.
     § 3553(a)(2)(B),
    (C).     And the District Court saw no aspects of Castro-Caicedo's
    -21-
    history   or    individual   characteristics        that   warranted    a     lower
    sentence.      See id. § 3553(a)(1).
    Castro-Caicedo's other challenge to his sentence is no
    stronger. He complains his sentence is "more than four times longer
    than the sentence of any of the other co-conspirator[s,] including
    the leader [of the conspiracy]."                 He acknowledges all of the
    coconspirators      pled   guilty    and    several    cooperated      with    the
    government, but he argues that "these factors still do not justify
    the district court's sentence."        Our precedent, however, indicates
    otherwise, United States v. Ayala-Vazquez, 
    751 F.3d 1
    , 34 (1st Cir.
    2014) (plea); United States v. Mateo-Espejo, 
    426 F.3d 508
    , 514 (1st
    Cir.   2005)     (cooperation),     and,    as    we   have   explained,       "[a]
    well-founded claim of disparity . . . assumes that apples are being
    compared to apples."       Mateo-Espejo, 
    426 F.3d at 514
    .        Having failed
    to show he is plainly similarly situated to those who received
    lesser sentences, his unpreserved disparity claim must fail.
    For these reasons, we affirm Castro-Caicedo's conviction
    and sentence.
