    FOR THE DISTRICT OF MASSACHUSETTS
    [Hon. Richard G. Stearns, U.S. District Judge]
    Before
    Howard, Selya and Kayatta,
    Circuit Judges.
    W. Daniel Deane, with whom Brian D. Duffy and Nixon Peabody
    LLP were on brief, for appellant.

    June 10, 2015
    SELYA, Circuit Judge.   This case is a poster child for
    the adage that easy money often leads to hard lessons. For several
    months, defendant-appellant Blessing Sydney Iwuala was awash in a
    flood of easy money as a Medicare-approved provider of durable
    medical equipment (DME).    But when the easy money dried up, he
    found himself facing criminal prosecution on multiple charges of
    health-care fraud.   The trial did not go well for the defendant,
    and he now challenges both his conviction and his sentence.   After
    careful consideration of his asseverational array, we affirm.
    I.   BACKGROUND
    In 2007, the defendant — a college graduate who had
    obtained a master's degree in business administration while in
    Nigeria — opened Above All Home Care and Medical Supply, Inc.
    (Above All), a DME supplier.   The following year, Above All gained
    Medicare approval, which authorized it to bill Medicare directly
    after filling DME prescriptions for Medicare beneficiaries.
    Despite securing this certification, the defendant's
    business lagged.   His fortunes changed dramatically when, in 2009,
    he entered into a business arrangement with John Nasky.         The
    defendant had known Nasky for two years both through their mutual
    involvement in the community of Nigerian immigrants in the Boston
    area and through the defendant's publication of a magazine covering
    Nigerian-American cultural and social events as far away as Texas.
    -2-
    The two men traveled in the same social circles and often saw each
    other at social events.
    Nasky operated his own medical supply and medical billing
    business with an office in Massachusetts.         He represented himself
    as having a client base in Texas.         Nasky had a problem: in June of
    2008, his supply company had been placed on payment suspension by
    Medicare due to a suspicion of fraudulent billing.             Nasky had
    prescriptions to fill and inventory in Texas, but he could not bill
    Medicare and expect to get paid.            So Nasky and the defendant
    reached an agreement: in exchange for a supply of blank Above All
    forms and the right to bill Medicare in Above All's name, Nasky
    would obtain DME prescriptions for Medicare beneficiaries, fill
    them from his inventory in Texas, and bill for the prescribed
    equipment in Above All's name.             Whatever proceeds Above All
    received would be split 65% to Nasky and 35% to the defendant.
    This was easy money for the defendant, who had to do no more than
    maintain his storefront in Massachusetts and funnel money to Nasky
    when Medicare paid Above All.
    The scheme was fraudulent through and through: the Above
    All billings submitted by Nasky were based largely on illicitly
    obtained   Medicare   beneficiary    identification     numbers,   forged
    prescriptions, and reimbursement requests for unnecessary medical
    equipment that in many instances was never delivered.
    -3-
    The plotters prospered: Above All billed Medicare for
    over $1,000,000 of DME between February and May of 2009 and
    received payments of more than $400,000.       But these halcyon days
    did not last long.    In July, Nasky was charged with Medicare fraud
    as a result of his involvement in a separate scheme.          Above All
    submitted no further claims to Medicare after that time, and its
    Medicare provider status was subsequently terminated.
    In due course, a federal grand jury sitting in the
    District of Massachusetts indicted the defendant on one count of
    conspiracy to commit health-care fraud, see 18 U.S.C. § 1349, four
    substantive counts of health-care fraud, see 
    id. §§ 2,
    1347, and
    one count of making a false statement to the government, see 
    id. § 1001.
       During an eight-day trial, the defendant maintained that
    his business arrangement with Nasky was above board, that he was an
    innocent dupe, and that he did not know at the time that any of the
    claims submitted were bogus.        The jury rejected his defense,
    finding him guilty on four counts.1      The district court imposed a
    42-month term of immurement, and this timely appeal followed.
    II.   ANALYSIS
    In this venue, the defendant challenges certain of the
    district   court's   evidentiary   rulings,   the   sufficiency   of   the
    government's proof, and the way in which the court calculated loss
    1
    One substantive health-care fraud charge was voluntarily
    dismissed by the government. See Fed. R. Crim. P. 48(a). The jury
    acquitted the defendant on the false statement count.
    -4-
    in constructing his guideline sentencing range.                 We examine these
    plaints one by one.
    A.    Evidentiary Rulings.
    The defendant reproves the district court's admission of
    evidence relating to Nasky's reputation and criminal history.                  We
    describe          what   transpired     before   addressing     the   defendant's
    argument.
    Prior to trial, the defendant moved in limine to preclude
    the government from adducing evidence that Nasky was known as a
    "419" — a slang term in the Nigerian-American community for
    "crook."2          The district court denied the motion subject to "the
    court's       policing     of     the   boundaries   of   any   so-called    '419'
    evidence."
    At trial, the government sought to show the defendant's
    guilty knowledge through, inter alia, his awareness of Nasky's
    reputation in the social circles that both of them frequented.                 To
    this       end,    the   government     called   Sunday   Joseph   Edem   (Nasky's
    coconspirator in a different fraud), who testified over objection
    that Nasky was "very flamboyant . . . . [a]lways dressing — showing
    off, like we call — in Nigeria . . . '419.'"
    Edem later testified, again over objection, that Nasky
    carried on a lifestyle in which he always wanted to be noticed and
    2
    The derivation of this term is direct: section 419 of
    chapter 38 of the Nigerian criminal code makes it a felony to
    commit theft by false pretenses.
    -5-
    treated    like    a    celebrity   or     a   "man   of    the   hour."    Without
    objection, Edem went on to testify how Nasky drew attention to
    himself at restaurants by paying everyone's bill or even tossing
    money out of buckets at parties as people followed him.                     In the
    same   vein,      Ana   Gonzalez    (who       had   been   employed   in   Nasky's
    Massachusetts office) testified without objection that Nasky often
    wore distinctive clothing and gold necklaces and rings.
    When asked specifically whether Nasky had a particular
    reputation in the community, Edem responded: "He had a reputation
    that you couldn't trust him with money. . . . You couldn't trust
    him with your wife . . . . You could not trust him in a business
    deal."     The jury also heard that Nasky had been convicted of
    health-care fraud in 2000; that he was arrested on July 29, 2009
    for his participation in a health-care fraud that did not involve
    the defendant; and that he later pleaded guilty to the latter
    charges.    The defendant himself elicited the information regarding
    Nasky's 2000 conviction, and he failed to object to the admission
    of evidence concerning Nasky's 2009 arrest and conviction.
    In his summation, the prosecutor referenced the testimony
    of both Edem and Gonzalez, stating:
    Could the defendant really not have
    known that Nasky was a fraud? . . . You heard
    testimony from [Edem]. . . . Remember his
    description about Nasky, the way he looked,
    the ridiculous jewelry that he wore, the
    particular way that he carried himself, with
    the money being thrown [out of] the buckets?
    . . . Ana Gonzalez also testified that Nasky
    -6-
    wore distinctive gold jewelry . . . . There
    were warning signs flashing everywhere that
    [Nasky] was not an honest businessman, someone
    not to be trusted.
    The prosecutor added: "[Y]ou now know that Nasky was someone who
    previously went to prison. . . . Is it really plausible that the
    defendant didn't know that either?"
    The defendant now contends that the district court abused
    its discretion in admitting the 419 testimony and other evidence of
    Nasky's appearance, reputation, and prior bad acts. This evidence,
    he says, was not admissible for any proper purpose and unfairly
    prejudiced him. The defendant adds that the prosecutor's summation
    (to   which    no   contemporaneous    objection   was   made)   improperly
    capitalized on evidence of Nasky's lifestyle and criminal history,
    in effect inviting the jury to infer guilt by association.
    We ordinarily review a district court's rulings admitting
    or excluding evidence for abuse of discretion.           See United States
    v. Gobbi, 
    471 F.3d 302
    , 311 (1st Cir. 2006).         But when a party has
    failed to object at trial either to an evidentiary ruling or to
    closing argument, our review is for plain error. See United States
    v. Raymond, 
    697 F.3d 32
    , 37-38 (1st Cir. 2012); United States v.
    Sepulveda, 
    15 F.3d 1161
    , 1188 (1st Cir. 1993). Here, the defendant
    objected to only some bits and pieces of the evidentiary mosaic
    that he now challenges, and much of that mosaic came in without
    objection.
    -7-
    In a veiled effort to skirt this looming obstacle, the
    defendant implies that his pretrial motion in limine served to
    preserve his objection to all of the evidence regarding Nasky's
    reputation and prior bad acts.     But this is a bridge too far:
    where, as here, a trial court "tentatively denies a pretrial motion
    in limine, or temporizes on it," any objections to the contested
    evidence must be renewed at trial. United States v. Noah, 
    130 F.3d 490
    , 496 (1st Cir. 1997).   Elsewise, plain error review obtains.
    See 
    Raymond, 697 F.3d at 38
    .
    At bottom, we are faced with a situation in which a
    handful of the district court's challenged evidentiary rulings
    engender abuse of discretion review while the remainder engender
    plain error review.     Still, we see no need to dismantle the
    evidentiary mosaic piece by piece. Even assuming, favorably to the
    defendant, that abuse of discretion review applies throughout, the
    defendant's challenge fails.
    To begin, we set to one side the defendant's lament about
    the 419 terminology and the evidence of Nasky's flamboyant habits
    and attire.   The only definition of "419" related to the jury was
    that the numerals referred to a "show off," and the meaning of the
    numerals is not otherwise common knowledge.   Consequently, Edem's
    use of this term simply became part of the evidentiary array that
    illustrated Nasky's attention-getting dress and lifestyle.
    -8-
    This evidence, along with the government's references to
    it in closing argument, may have needlessly embellished the jury's
    image of Nasky. Nevertheless, it could not have carried great
    weight in proving the defendant's knowledge of fraud.              Whether it
    served, though, as a basis for an inference that fit as a piece of
    a larger picture is a question that the jurors were fairly left to
    answer.
    Next,   we   reject   the    defendant's    assertion    that   the
    evidence of Nasky's reputation as a con man was barred by Federal
    Rule of Evidence 404.      Rule 404(a)(1) precludes the admission of
    evidence of "a person's character or character trait" for the
    purpose of proving that "on a particular occasion [that] person
    acted in accordance with the character or trait."                  That same
    evidence may be admitted, though, when it has special relevance to
    an issue in the case (such as knowledge or intent), as long as
    neither bad character nor propensity is a link in the inferential
    chain.    See United States v. Salameh, 
    152 F.3d 88
    , 123 (2d Cir.
    1998); see also United States v. Varoudakis, 
    233 F.3d 113
    , 118 (1st
    Cir. 2000) (discussing "special relevance" in context of Federal
    Rule of Evidence 404(b)).
    In the case at hand, the evidence of Nasky's reputation
    in the community was specially relevant: it was competent to show
    that when the business arrangement evolved, Nasky's reputation
    should    have   forewarned      the    defendant     against   taking     his
    -9-
    representations at face value.          After all, evidence of a person's
    reputation may be admitted to show the knowledge or state of mind
    of some other person.          For example, in an extortion case, a
    defendant's reputation for violence or association with organized
    crime may be admitted to show the victim's state of mind, including
    his reasonable belief in the defendant's threat of violence.                 See,
    e.g., United States v. Goodoak, 
    836 F.2d 708
    , 714-15 (1st Cir.
    1988); United States v. Russo, 
    708 F.2d 209
    , 214 (6th Cir. 1983).
    Similarly, a tenant's reputation as a drug dealer may be admitted
    to show a landlord's knowledge that the tenant was using the
    premises for drug trafficking. See, e.g., United States v. Certain
    Real Prop. & Premises, 
    945 F.2d 1252
    , 1260 (2d Cir. 1991).                So it
    is    here:   evidence   of   Nasky's   reputation     as   a    fraudster    was
    admissible to prove the defendant's knowledge that the business
    venture that Nasky proposed was a scam.
    In an effort to snatch victory from the jaws of defeat,
    the defendant asserts that the reputation evidence should not have
    been admitted because proof was lacking that the defendant knew of
    Nasky's reputation for fraud.           This assertion is triply flawed.
    For one thing, the defendant failed to challenge the admission of
    the    reputation   evidence    in   the    court   below   on    this   ground.
    Although the defendant objected to this evidence on relevancy
    grounds, an objection to the admission of evidence on one ground
    does not preserve other grounds for appeal.            See United States v.
    -10-
    Holmquist, 
    36 F.3d 154
    , 168 (1st Cir. 1994); see also Fed. R. Evid.
    103(a)(1).     For another thing, the defendant's opening brief in
    this court never raised the lack-of-knowledge point.               While the
    defendant did advance the argument in his reply brief, that was too
    little and too late.      See United States v. Torres, 
    162 F.3d 6
    , 11
    (1st Cir. 1998); Sandstrom v. ChemLawn Corp., 
    904 F.2d 83
    , 86 (1st
    Cir. 1990).
    Even assuming that this argument was merely forfeited
    rather than waived, there was surely no plain error in admitting
    the reputation evidence.          Other proof allowed the jury to infer
    that the defendant had the opportunity to learn the gist of what
    Edem knew about Nasky's reputation in their shared community.
    After all, the defendant knew Nasky personally long before the
    scheme began and told investigators that he and Nasky traveled in
    the same circles.       Given this predicate, there was no clear or
    obvious error in the admission of the reputation evidence.                See
    United    States   v.   Duarte,    
    246 F.3d 56
    ,   60   (1st   Cir.   2001)
    (requiring, at a minimum, "clear or obvious error" to show plain
    error and overcome a forfeiture).
    Evidence of Nasky's 2009 arrest was also admissible.
    That evidence was introduced not to show Nasky's bad character but,
    rather, to show why the defendant's dealings with Nasky came to an
    end.     Such evidence may be admitted in a conspiracy case to show
    the background and development of the conspiratorial relationship
    -11-
    or to fill in details of the plot.    See United States v. Escobar-de
    Jesús, 
    187 F.3d 148
    , 169 (1st Cir. 1999); United States v. Pitre,
    
    960 F.2d 1112
    , 1119 (2d Cir. 1992).
    The prosecutor's summation does not change this calculus.
    Once evidence is properly introduced, either party may ask the jury
    to draw reasonable inferences from it concerning issues that are
    fairly in the case.    See United States v. Pires, 
    642 F.3d 1
    , 14
    (1st Cir. 2011); United States v. O'Shea, 
    426 F.3d 475
    , 485 (1st
    Cir. 2005).   That is what happened here.      The prosecutor argued
    simply that Nasky's appearance and self-promotion gave some warning
    signs to the defendant that Nasky was not a legitimate businessman.
    Similarly, we reject the defendant's muddled suggestion
    that the evidence of Nasky's prior conviction for fraud was barred
    by Rule 404. To be sure, Rule 404(b)(1) precludes the admission of
    evidence of "a crime, wrong, or other act" to prove propensity.
    But that proscription does not apply at all in the circumstances of
    this case: Nasky's 2000 conviction was not brought up by the
    government but, rather, by the defendant.3    A party cannot be heard
    to complain about the prejudicial effect of evidence that he
    himself introduced.4   See United States v. Majeroni, 
    784 F.3d 72
    ,
    3
    The defendant does not assign error to the admission of
    evidence of Nasky's conviction following his 2009 arrest (and, in
    any event, that evidence was admitted without objection).
    4
    We add that when the prosecutor referred to the conviction
    in his closing argument, he did so only for the permissible purpose
    of showing the defendant's knowledge and intent. See Raymond, 697
    -12-
    77 (1st Cir. 2015); United States v. Munson, 
    819 F.2d 337
    , 342 (1st
    Cir. 1987).
    The defendant further posits that the admission of the
    reputation evidence, in concert with the evidence of Nasky's 2000
    conviction and 2009 arrest and conviction, transgressed Federal
    Rule of Evidence 403.   This is a heavy lift: "[O]nly rarely — and
    in extraordinarily compelling circumstances — will we, from the
    vista of a cold appellate record, reverse a district court's on-
    the-spot judgment concerning the relative weighing of probative
    value and unfair effect." 
    Raymond, 697 F.3d at 38
    (quoting Freeman
    v. Package Mach. Co., 
    865 F.2d 1331
    , 1340 (1st Cir. 1988)).    There
    are no such compelling circumstances here.      The central issue in
    the case was whether the defendant was hoodwinked by Nasky (as he
    claimed) or whether he knowingly participated in the scheme to
    defraud Medicare (as the government claimed).    Evidence of Nasky's
    reputation in their shared community was probative as to whether
    the defendant knowingly participated in or was willfully blind to
    the fraudulent design of the scheme that Nasky proposed.        See,
    e.g., 
    Noah, 130 F.3d at 496
    (concluding that when defendant "staked
    his defense on the proposition that he was an innocent dupe,
    victimized by a lawless employee," prior bad act evidence was
    F.3d at 38; see also Fed. R. Evid. 404(b)(2). The conviction was
    never used by the government to show propensity.
    -13-
    highly relevant to show "guilty knowledge, the existence of a
    criminal plan, and the absence of mistake").
    Nor can it be said that the district court abused its
    broad discretion in ruling that the probative value of this
    evidence was not substantially outweighed by the prospect of unfair
    prejudice.    Before the need to exclude particular evidence arises,
    "there must be a significant tipping of the scales against the
    evidentiary worth of the proffered evidence."           United States v.
    Aguilar-Aranceta, 
    58 F.3d 796
    , 800 (1st Cir. 1995) (internal
    quotation mark omitted).      Here, the evidence bore on a critical
    element of the charged crimes — the defendant's mens rea. Although
    the evidence painted a manifestly unattractive picture of Nasky and
    certainly hurt the defendant's chances at trial, Rule 403 has never
    been interpreted to bar evidence simply because it is prejudicial.
    See United States v. Rodriguez-Estrada, 
    877 F.2d 153
    , 156 (1st Cir.
    1989) ("By design, all evidence is meant to be prejudicial[.]")
    The rule bars only unfair prejudice, see 
    id., and we
    discern no
    unfair prejudice here.
    The prosecutor's closing argument does not shift the
    balance.     The prosecutor scrupulously refrained from suggesting
    that   Nasky's    character   or   reputation   alone     evidenced   the
    defendant's guilt.     Nor did he ask the jury to infer, either
    expressly or by implication, that the defendant must have been
    complicit in the scheme merely because he associated with Nasky.
    -14-
    Instead, the prosecutor used the challenged evidence only as one of
    several    points   supporting       the    government's   position    that   the
    defendant must have realized the fraudulent nature of his dealings
    with Nasky.
    B.   Sufficiency of the Evidence.
    We   turn    next   to    the    defendant's   challenge    to    the
    sufficiency of the evidence. This challenge was preserved by means
    of a motion for judgment of acquittal, see Fed. R. Crim. P. 29,
    which the district court denied.              We review this denial de novo.
    See United States v. Gomez, 
    255 F.3d 31
    , 35 (1st Cir. 2001).
    In evaluating a challenge to the sufficiency of the
    evidence, a reviewing court must scrutinize all the evidence in the
    light most hospitable to the government's theory of the case.                 See
    
    id. The court
    then must determine whether the evidence, when
    viewed in that light and with all permissible inferences drawn in
    favor of the verdict, would allow a "rational factfinder to
    conclude beyond a reasonable doubt that the defendant committed the
    charged crime." 
    Id. (internal quotation
    mark omitted). Under this
    regime, all credibility disputes must be resolved in favor of the
    verdict.    See United States v. Piper, 
    298 F.3d 47
    , 59 (1st Cir.
    2002); United States v. Martin, 
    228 F.3d 1
    , 10 (1st Cir. 2000).
    So, too, the court may not speculate as to the weight afforded to
    individual pieces of evidence: rather, it must recognize that the
    jury need not evaluate each piece of evidence in isolation but may
    -15-
    draw conclusions from the evidence as a whole.             See 
    Martin, 228 F.3d at 10
    ; United States v. Spinney, 
    65 F.3d 231
    , 234 (1st Cir.
    1995).
    In the last analysis, the government need not disprove
    every theory compatible with the defendant's innocence.                  See
    
    Spinney, 65 F.3d at 234
    .            It is enough that the verdict is
    supported by a "plausible rendition of the record."               
    Gomez, 255 F.3d at 35
    (internal quotation mark omitted).
    We move now from the general to the specific, starting
    with the conspiracy count.      The defendant does not challenge the
    government's proof of the existence of the conspiracy. Instead, he
    zeroes in on the two remaining elements of the offense, arguing
    that the evidence was too thin to prove either that he knew of the
    existence of the conspiracy or that he knowingly participated in
    it.    Ably represented, he slices and dices the government's case,
    characterizing it as circumstantial and asserting that each piece
    of circumstantial evidence, viewed in isolation, admits of an
    equally plausible inference compatible with innocence.              On this
    view, he submits, the jury must perforce have entertained a
    reasonable doubt as to his guilt.            See United States v. Flores-
    Rivera, 
    56 F.3d 319
    , 323 (1st Cir. 1995).
    With respect to the three substantive counts of health-
    care     fraud,   the   defendant    makes    much   the   same    argument.
    Specifically, he asserts that the evidence was insufficient to
    -16-
    prove his knowledge of, and his specific intent to execute, a fraud
    on Medicare vis-à-vis each of the named beneficiaries.
    To prove conspiracy to commit health-care fraud under 18
    U.S.C. § 1349, the government must prove beyond a reasonable doubt
    that an agreement existed to commit the underlying substantive
    offense (here, health-care fraud under 18 U.S.C. § 1347), that the
    defendant knew of the agreement, and that he voluntarily joined it
    with the intent to commit the underlying offense.                See United
    States v. Willett, 
    751 F.3d 335
    , 339 (5th Cir. 2014); 
    Gomez, 255 F.3d at 35
    .    Guilty knowledge and intent may be proven solely by
    circumstantial evidence.          See United States v. O'Brien, 
    14 F.3d 703
    , 706 (1st Cir. 1994).
    In this case, the government adduced evidence from which
    a rational jury could have concluded that the defendant both knew
    of   the   existence   of   the    conspiracy   to   defraud   Medicare   and
    voluntarily chose to participate in it.         Nasky did not come to the
    defendant as a stranger: the two men had known each other for a
    substantial period of time, traveled in the same circles, and
    exchanged telephone calls on average monthly during the two years
    preceding the birth of the scheme.
    What is more, the terms of their business arrangement
    were highly suspicious. Nasky offered to give the defendant 35% of
    the revenue from prescriptions and inventory already in hand in
    exchange for nothing more than the use of Above All's name and
    -17-
    Medicare provider number.         Things that sound too good to be true
    usually   are,    and   the   defendant   knew   that     he   was   being   paid
    substantial sums for doing nothing more than giving Nasky free rein
    with Above All's forms and provider number and remitting Nasky's
    share to him when payments were received.            Furthermore, the jury
    rationally could have found that the defendant learned that Nasky
    was no longer able to bill Medicare through his own company — a
    fact   that    Nasky    freely   shared   with   others   such   as   Edem   and
    Gonzalez.      From that point forward, the grounds for suspicion
    escalated.
    There was more.     Remittance notices, received by Above
    All, accompanied each Medicare payment.                 Each notice set out
    information about the particular beneficiary, the item or items
    billed for that beneficiary, and the amount Medicare paid for each
    such item.     For 67 out of 88 Texas-based beneficiaries, Above All
    billed Medicare in the same amount for the same type of equipment
    — typically, $12,650 for a power wheelchair, related accessories,
    multiple braces, and a heat lamp.           Even the most fervent believer
    in coincidence would have raised an eyebrow over those remarkable
    similarities.      See, e.g., United States v. Cruz-Arroyo, 
    461 F.3d 69
    , 75 (1st Cir. 2006) (concluding that one "would have to believe
    in the Tooth Fairy" to believe a certain set of facts "merely
    coincidental" (internal quotation mark omitted)).
    -18-
    Other evidence made pellucid that the linkage forged
    between the defendant and Nasky was not a legitimate arm's-length
    business relationship.         The defendant transferred substantial sums
    to Nasky, allegedly for equipment purchases — yet during the
    Medicare investigation he was unable to produce even a single
    invoice to support his averment that Above All actually bought
    equipment through Nasky.            To add fuel to the fire, these monetary
    transfers   took    place      in    unorthodox    ways:      sometimes    in   cash,
    sometimes by wire transfer, sometimes by check, and not always to
    Nasky or to his business (on occasion, monies were sent to Nasky's
    wife or to her beauty supply company).                   Even after Nasky was
    arrested in 2009, the defendant sent him money in jail.
    Importantly, Nasky told the defendant that he needed his
    share of the proceeds quickly in order to "take care of some
    people."     The defendant's awareness of that fact was strong
    evidence of his guilty knowledge — and his awareness was heightened
    when, at a later point during the conspiracy, Nasky stated to the
    defendant   in     so   many    words    that     he   paid    people     to    obtain
    prescriptions.
    The pattern of telephone calls between the defendant and
    Nasky likewise indicated a connection more sinister than one would
    expect of a business owner and an independent service provider.
    For example, on May 6, 2009 — at the height of the fraud — a
    Medicare auditor conducted an unannounced site inspection at Above
    -19-
    All.    During this inspection, the auditor reviewed a sampling of
    Above All's customer files and compared its inventory to its recent
    Medicare billings.       The auditor asked the defendant to provide
    invoices to authenticate Above All's recent equipment billings
    because its inventory seemed woefully scant in comparison to those
    billings.     On that same day, the defendant and Nasky exchanged 11
    telephone calls.       One of those occurred between the auditor's
    arrival at Above All and the start of the defendant's interview
    with her, and seven others occurred after the site visit had
    concluded.      On the following day, there were seven more calls
    between the defendant and Nasky.          Although the defendant tries to
    put    an   innocent   face   on   this   avalanche   of   calls,   the   jury
    reasonably could have inferred that the avalanche was sparked by
    more than a simple request for copies of invoices.
    There was still more.        The evidence indicates that the
    defendant hid his business relationship with Nasky.             Over 90% of
    Above All's claims involved Texas-based beneficiaries.              Yet, the
    auditor who conducted the May 6 site visit testified that the files
    she reviewed concerned only Massachusetts-based beneficiaries (none
    from Texas).      Furthermore, when she requested information about
    Above All's inventory supply, the defendant responded that he
    purchased equipment from another (legitimate) company and never
    said a word about his significant ties with Nasky.              Nor was the
    defendant's penchant for keeping people in the dark about his
    -20-
    supposedly legitimate dealings with Nasky limited to the Medicare
    auditor.     A witness who worked for Above All throughout 2009
    testified that he was not aware that the defendant had any business
    relationship with Nasky.
    Finally, the reputation evidence buttresses the other
    evidence.    Nasky offered the defendant a business arrangement that
    was wildly unconventional and promised great rewards for minimal
    effort.     Given Nasky's known reputation as a fraudster,5 the jury
    could have used this evidence as one of several pieces of evidence
    contributing to a reasonable inference of the defendant's guilty
    knowledge and willing participation.      See, e.g., United States v.
    Mitchell, 
    31 F.3d 628
    , 631, 633 (8th Cir. 1994).
    To say more would be to paint the lily.       We agree with
    the defendant that the tapestry of the government's case is woven
    from strands of circumstantial evidence, and many of these strands,
    taken singly, might admit of an innocent explanation premised on
    the   defendant's   professed   naivety   and   Nasky's   deftness   as   a
    fraudster.     But the sum of an evidentiary presentation often is
    greater than its individual parts. See Bourjaily v. United States,
    5
    Edem's testimony largely concerned Nasky's reputation in
    Texas. But the defendant, wearing his journalist's hat, traveled
    to Texas on several occasions to report on social functions in the
    Nigerian-American community for his magazine.      The defendant's
    presence in Texas, together with evidence that he knew Nasky well,
    that the two spoke regularly, and that they traveled in the same
    social circles, afforded a sufficient foundation for a finding that
    he was aware of Nasky's dubious reputation in Texas as well as
    Massachusetts.

    Region, Inc., 
    668 F.3d 25
    , 34 (1st Cir. 2012).     Particularly in
    fraud cases, it is familiar lore that the government may carry its
    burden of proof wholly through circumstantial evidence. See, e.g.,
    
    O'Brien, 14 F.3d at 706
    .
    Our duty here is not to reweigh the evidence, see 
    Martin, 228 F.3d at 10
    , but to evaluate whether a rational jury could have
    concluded beyond a reasonable doubt that the defendant knowingly
    and willfully conspired to commit health-care fraud, see 
    Willett, 751 F.3d at 339
    ; 
    Gomez, 255 F.3d at 35
    .      Given the weight and
    texture of the evidence as a whole, we believe that the jury, using
    common sense to draw a series of reasonable inferences, reached
    just such a conclusion.6   See 
    Spinney, 65 F.3d at 238
    ("Chains of
    inference are a familiar, widely accepted ingredient of any process
    of ratiocination.   This method of reasoning . . . should not be
    forbidden to a criminal jury.").
    We need not tarry over the sufficiency of the evidence on
    the three substantive counts of Medicare fraud.       The district
    court's instructions permitted the jury to convict the defendant on
    these charges either as a principal, see 18 U.S.C. § 1347, or as an
    aider and abettor, see 
    id. § 2.
    6
    In light of this holding, we have no occasion to consider
    the government's alternative theory that the defendant's guilty
    knowledge was proven by evidence of his willful blindness.
    -22-
    Proof of a violation of 18 U.S.C. § 1347 requires a
    showing that the defendant knowingly and willfully executed a
    scheme to defraud a government health-care program.       See 
    Willett, 751 F.3d at 339
    .    In criminal cases, willfulness generally means
    that an act was undertaken with a "bad purpose," that is, with
    knowledge that the act is unlawful.      Bryan v. United States, 
    524 U.S. 184
    , 191-92 (1998).    Aiding and abetting requires proof that
    the defendant "consciously shared the principal's knowledge of the
    underlying criminal act, and intended to help the principal"
    accomplish it. United States v. Taylor, 
    54 F.3d 967
    , 975 (1st Cir.
    1995).   In the case of health-care fraud, proof of guilt either as
    a principal or as an aider or abettor requires proof of specific
    intent, which may be established by circumstantial evidence.        See
    
    Willett, 751 F.3d at 339
    ; 
    Taylor, 54 F.3d at 975
    .
    Whatever the theory, the evidence here is sufficient to
    support the jury's verdict on each substantive count of health-care
    fraud.   Each count was premised on a Medicare claim submitted by
    Above All for a specified Texas-based beneficiary who testified at
    trial. The circumstances of these claims shared many of the badges
    of fraud that characterized the overall scheme.      All of the claims
    were   predicated   on   forged   prescriptions;   used   an   identical
    (fraudulent) diagnosis code; and resulted in a billing by Above All
    -23-
    to Medicare for no fewer than 11 articles of unnecessary and/or
    unwanted medical equipment.7
    Viewing this evidence in the reflected light of the
    abundant evidence of widespread fraud, we think it without serious
    question that a rational jury could have concluded — as this jury
    did — that the defendant knowingly and willfully both perpetrated
    and   aided       and   abetted        health-care    fraud     vis-à-vis           these
    beneficiaries.
    C.    Sentencing.
    The defendant's final assignment of error implicates his
    sentence.     At the disposition hearing, the district court set the
    guideline sentencing range (GSR) at 51 to 63 months, premised on a
    criminal history category of I and a total offense level of 24.
    The   offense     level   was     driven    in   large   part      by     a    16-level
    enhancement for an intended loss of more than $1,000,000 but not
    more than $2,500,000.            See USSG §2B1.1(b)(1)(I)-(J).                The court
    sentenced the defendant to a below-the-range incarcerative term of
    42 months.
    On    appeal,   the       defendant     contests      only       the    loss
    calculation. He argues that the sentencing court erred by treating
    the total amount billed to Medicare as intended loss, failing to
    credit    repayments      that    the    defendant    made    to    Medicare,         and
    7
    To make the cheese more binding, one of these three
    beneficiaries identified the defendant as the person who had
    delivered the unwanted medical equipment to her home.
    -24-
    including billings for certain purportedly legitimate claims.    We
    review the district court's application of the relevant sentencing
    guidelines (including its selection of a loss-calculation method)
    de novo.   See United States v. Alphas, ___ F.3d ___, ___ (1st Cir.
    2015) [No. 14-2228, slip op. at 9]; United States v. Pennue, 
    770 F.3d 985
    , 991 (1st Cir. 2014); United States v. Stergios, 
    659 F.3d 127
    , 135 (1st Cir. 2011).
    The guideline that deals with theft and fraud offenses,
    including health-care fraud, provides that the defendant's offense
    level should be enhanced in proportion to the loss associated with
    the offense. See USSG §2B1.1(b)(1); 
    id. at App.
    A. In determining
    the loss amount, the sentencing court must consider the greater of
    actual or intended loss.    See United States v. Innarelli, 
    524 F.3d 286
    , 290 (1st Cir. 2008); USSG §2B1.1, comment. (n.3(A)).    Actual
    loss is the "reasonably foreseeable pecuniary harm that resulted
    from the offense."    USSG §2B1.1, comment. (n.3(A)(i)).   Intended
    loss is "the pecuniary harm that was intended to result from the
    offense," including harm that "would have been impossible or
    unlikely to occur."   
    Id. at n.3(A)(ii).
       These principles inform
    the defendant's assignment of sentencing error.
    The parties — who agree on little else — do not dispute
    that actual loss is no greater than $446,712 (the total paid by
    Medicare to Above All).       Here, however, the sentencing court
    -25-
    thought that intended loss controlled — and its calculation of
    intended loss is more controversial.
    At sentencing, the government urged the court to treat as
    intended loss the face amount of the fraudulent claims that Above
    All billed to Medicare ($1,097,160).           This amount includes the
    claims associated with 90 beneficiaries, two from Massachusetts and
    88 from Texas.     The defendant countered that the amount billed to
    Medicare was not a suitable basis for a finding of intended loss.
    He argued instead that the proper measure of intended loss was the
    amount actually paid by Medicare.             In support, he noted that
    Medicare pays claims according to a fee schedule predicated in part
    on a percentage of the amount claimed and, therefore, always pays
    less than the amount billed.        See 42 C.F.R. § 414.210 (explaining
    that Medicare generally pays for DME "on the basis of 80 percent of
    the lesser of . . . [t]he actual charge for the item [or] [t]he fee
    schedule amount for the item").            The court below resolved this
    contretemps in favor of the government.8
    Even though the defendant was sentenced in 2013, the
    district   court    applied   the    2008    edition   of   the   sentencing
    guidelines (the edition in effect when the offenses of conviction
    8
    The defendant asserts that the district court mistakenly
    thought that he was arguing for a sentence based on actual loss,
    not intended loss. A careful reading of the sentencing transcript
    persuades us that the court understood the thrust of the
    defendant's argument.
    -26-
    occurred).9    The court proceeded to treat the amount billed to
    Medicare as evidence of the amount of intended loss, set the loss
    amount in excess of $1,000,000, and boosted the defendant's offense
    level by 16 levels.    The defendant assigns error to the court's
    methodology.
    Under the 2008 guidelines, as now, a sentencing court is
    permitted to determine the amount of intended loss based on a
    reasonable estimate. See Alphas, ___ F.3d at ___ [slip op. at 19];
    United States v. McCoy, 
    508 F.3d 74
    , 79 (1st Cir. 2007).   Compare
    USSG §2B1.1, comment. (n.3(C)) (Nov. 2014), with 
    id. (Nov. 2008).
    Intended loss may include even those losses that were "impossible
    or unlikely to occur," such as an insurance fraud where the claim
    exceeds the insured value. USSG §2B1.1, comment. (n.3(A)(ii)). In
    cases of health-care fraud, courts have regularly held that the
    amount billed to Medicare is prima facie evidence of intended loss.
    See, e.g., United States v. Isiwele, 
    635 F.3d 196
    , 203 (5th Cir.
    9
    In 2011, the Sentencing Commission amended the commentary to
    USSG §2B1.1 to make explicit that where a defendant is convicted of
    an offense involving theft from a government health-care program,
    "the aggregate dollar amount of fraudulent bills submitted to the
    . . . program shall constitute prima facie evidence of the amount
    of the intended loss, i.e., is evidence sufficient to establish the
    amount of the intended loss, if not rebutted." USSG App. C, Amend.
    749 (codified at USSG §2B1.1, comment. (n.3(F)(viii))). Although
    this amendment may have applied retroactively, see, e.g., David v.
    United States, 
    134 F.3d 470
    , 476 (1st Cir. 1998); Isabel v. United
    States, 
    980 F.2d 60
    , 62 (1st Cir. 1992), the government has not
    pressed that point.     Consequently, we deem any such argument
    waived. See United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir.
    1990).
    -27-
    2011); United States v. Miller, 
    316 F.3d 495
    , 504 (4th Cir. 2003).
    These     decisions     draw   their    essence    from    the   long-standing
    presumption in the law that a "bill is a bill," that is, that the
    face amount of a bill is presumptive evidence of the amount that
    the person who submits it expects to obtain.              
    Miller, 316 F.3d at 504
    .    This is a variation of the hoary rule that the face value of
    a fraudulent instrument may be treated as evidence of the amount
    that the fraudster intended to swindle.             See, e.g., 
    Stergios, 659 F.3d at 135-36
    ; United States v. Blastos, 
    258 F.3d 25
    , 30 (1st Cir.
    2001); United States v. Geevers, 
    226 F.3d 186
    , 192-93 (3d Cir.
    2000); see also United States v. Alli, 
    444 F.3d 34
    , 39 (1st Cir.
    2006) (using limits on stolen credit cards as measure of intended
    loss).
    We   most    recently   followed      this   practice   in   Alphas.
    There, we held — in a case involving multiple insurance claims
    "demonstrably rife with fraud" — that the sentencing court could
    rely on the face amount of the claims as evidence of intended loss.
    See Alphas, ___ F.3d at ___ [slip op. at 19].                "[T]he burden of
    production will then shift to the defendant, who must offer
    evidence to show" why the loss figure should be set at a lower
    amount.    Id. at ___ [slip op. at 19].           "After the record is fully
    formed, the sentencing court must determine the amount of loss that
    the government (which retains the burden of proof) is able to
    establish."      Id. at ___ [slip op. at 19].        That determination need
    -28-
    only reflect "a reasonable estimate of the loss." Id. at ___ [slip
    op. at 19](quoting USSG §2B1.1, comment. (n.3(C))).
    Applying this case law, we hold that the sentencing court
    did   not   err   in   treating   the    amounts    billed   to   Medicare    as
    presumptive evidence of the amount of intended loss. But this does
    not   end   the   matter:   the   defendant    argues    that     even   if   the
    sentencing court appropriately used the amounts billed to Medicare
    as a starting point, he rebutted any presumption that those amounts
    were a suitable proxy for intended loss.             This argument will not
    wash.
    Intended loss is the loss that a person standing in the
    defendant's shoes reasonably would have expected to cause at the
    time he perpetrated the fraud.          See id. at ___ [slip op. at 9-10];
    
    Innarelli, 524 F.3d at 291
    . The test for intent is based primarily
    on the defendant's objectively reasonable expectations at the time

    The defendant argues that he intended to defraud Medicare
    of no more than what Medicare actually paid.            In support, he says
    that any DME provider would have known that Medicare would not pay
    the full amount billed.           But this is too myopic a view: it
    overlooks that the defendant, at the time of the fraud, was a DME
    -29-
    provider who had joined forces with an inveterate fraudster in an
    attempt to bilk Medicare out of as much as the traffic would bear.
    There is no reason to think that a fraudster in that position would
    have intended to scoop anything less than as much as he could from
    Medicare. See 
    Geevers, 226 F.3d at 193
    (observing that even though
    a check kiter "may not have expected to get it all, he could be
    presumed to have wanted to").   At bottom, the defendant's problem
    is that, professing great ignorance about the whole scheme, he
    offered no direct evidence that he expected Medicare to pay less
    than his cohort billed; and the indirect evidence that a reasonable
    person would have so expected is not strong.   In particular, there
    is no evidence in this record that would have compelled the
    district court to find that the defendant knew that the amount
    billed was more than the scheduled amounts that Medicare routinely
    paid.
    The defendant has a final argument related to the loss
    amount.   He contends that he displayed an entitlement to credits
    that he did not receive.    Some background is needed to put this
    contention into perspective.
    The sentencing court arrived at $1,097,160 for intended
    loss.   The defendant submits that this figure should be offset by
    $90,838 based on (i) sums that he refunded to Medicare during the
    course of the fraudulent scheme (totaling $46,588) and (ii) sums
    associated with purportedly legitimate claims for four specific
    -30-
    beneficiaries (totaling $44,250).      But even if the defendant is
    correct — a matter on which we take no view — these offsets would
    not reduce the intended loss amount below the cutoff point for the
    16-level enhancement. See USSG §2B1.1(b)(1)(I) (establishing floor
    for enhancement at more than $1,000,000).    Accordingly, resolving
    the defendant's contentions would serve no useful purpose; any
    error in failing to offset these amounts would be harmless.     See
    Williams v. United States, 
    503 U.S. 193
    , 203 (1992); United States
    v. Gerhard, 
    615 F.3d 7
    , 34 (1st Cir. 2010).
    III.   CONCLUSION
    We need go no further. For the reasons elucidated above,
    the defendant's conviction and sentence are
    Affirmed.
