    MCCAFFERTY, District Judge.          This medical malpractice
    suit   arises   from   obstetric   care     provided    to   the     plaintiff-
    appellee,    Jeannette    Rodríguez-Valentin      in connection with the
    birth of her minor son, DALR.         A jury found appellant Doctors'
    Center Hospital (Manati), Inc. ("Doctors' Center") liable for 8
    percent of a $14,296,000 total award.         Doctors' Center appeals the
    denial of its post-verdict motions for judgment as a matter of
    law, for a new trial, and for remittitur under Federal Rules of
    Civil Procedure 50 and 59.       We affirm.
    BACKGROUND
    I.          Complications During DALR's Birth
    Rodríguez-Valentin     gave   birth    to   DALR    by    caesarean
    section at Doctors' Center in Puerto Rico in late September 2008.
    A few months after his birth, DALR was diagnosed with cerebral
    palsy.      Rodríguez-Valentin alleged that DALR's cerebral palsy
    resulted from, or was exacerbated by, medical malpractice by
    treating physicians and nurses during the late stages of her
    pregnancy and DALR's delivery.       This appeal by Doctors' Center is
    pertinent only to the medical care provided by treating nurses
    employed by Doctors' Center.
    The nurses' alleged malpractice occurred during DALR's
    birth.   Doctors' Center's nurses, per a physician's order, began
    administering    the     pharmaceutical   drug    Pitocin      to    Rodríguez-
    Valentin at about 9:31 A.M. on September 25 while she was in labor.
    - 2 -
    The Pitocin was intended to aid delivery by reducing the time
    between Rodríguez-Valentin's contractions.
    Soon after the nurses administered Pitocin, however,
    DALR's "heart rate variability," as documented by a monitor placed
    on    Rodríguez-Valentin's        abdomen,      dropped     to    a     "very    minimal
    level."      At trial, Rodríguez-Valentin's expert witness, Dr. Bruce
    Halbridge, testified that DALR's heart rate variability had been
    within    an    appropriate       range    before     the    nurses      administered
    Pitocin.       Dr. Halbridge explained that the drop in heart rate
    variability from that appropriate range showed that DALR was not
    receiving enough oxygen, glucose, or blood through the placenta.
    Dr. Halbridge noted that such a loss of heart rate variability is
    the   most     important    signal     that    a    soon-to-be-born        baby    lacks
    sufficient oxygen.
    Dr.   Halbridge    identified       where    and   when     the    nurses
    should     have      seen   the   changes      in    heart       rate    variability.
    Specifically,        according    to   Dr.     Halbridge,     DALR's       heart    rate
    variability       issues    occurred      in   several,     sometimes      prolonged,
    "episodes" throughout Rodríguez-Valentin's labor.                       Dr. Halbridge
    testified that, in his opinion, by the third "episode" of decreased
    heart rate variability, the treating nurses should have stopped
    administering Pitocin, placed Rodríguez-Valentin on her left side,
    increased her IV fluid intake, provided her with an oxygen mask,
    - 3 -
    and notified a physician about the drop in DALR's heart rate
    variability.
    Rodríguez-Valentin's labor continued for eight hours
    after the nurses began administering Pitocin.              During this time
    the treating nurses failed to recognize or act on the drop in
    DALR's   heart   rate   variability,     failed   to   stop   administering
    Pitocin, and failed to notify any physician about the change in
    DALR's heart rate variability.
    Dr. Halbridge testified that oxygen deprivation during
    the delivery increased DALR's brain damage and aggravated his
    cerebral palsy.    Dr. Halbridge noted that, had the nurses notified
    a physician, the caesarean section could also have been expedited,
    which likely would have reduced the severity of DALR's injuries
    because he would have spent less time without sufficient oxygen.
    In    defense   of   the   nurses'   conduct,   Doctors'   Center
    offered the testimony of two expert witnesses in obstetrics, Dr.
    Alberto de la Vega Pujol and Dr. Edgar Solis.              These physicians
    disagreed with Dr. Halbridge, opining that DALR's heart rate
    variability was adequate during labor and that there was no
    evidence that DALR suffered any oxygen deficiency during delivery.
    Dr. Solis also testified that neuroradiological testing conducted
    after DALR's birth supported his opinion that DALR did not suffer
    from oxygen deficiency during delivery.
    - 4 -
    II.         Testimony about DALR's Life Care Expenses
    Rodríguez-Valentin    claimed        considerable         damages   for
    DALR's future life care costs.            Specifically, Gerri Pennachio
    testified for Rodríguez-Valentin as a "life care planning expert,"
    opining about the       yearly cost of DALR's            care and treatment.
    According   to   Pennachio,   these      costs    would      include       necessary
    equipment, doctor visits, testing, and physical therapy, among
    other   items.    Pennachio    determined        that    DALR    would      require
    $278,021.57 per year until age 18. After age 18, Pennachio opined,
    DALR would need $379,235.57 per year.
    On   cross-examination,           Doctors'       Center        dissected
    Pennachio's calculations, asking her whether she had offset the
    yearly amounts by contributions made by insurance or the government
    and whether she had based her calculations on costs in Florida
    (where DALR lived at the time of trial) as opposed to Massachusetts
    (where DALR had lived before moving to Florida).                           Pennachio
    acknowledged that she had not offset her calculations based on
    contributions made by insurance or the government.                    She did not
    dispute that she derived her calculations from cost information in
    Massachusetts    even   though,   at    the    time     of   trial,     Rodríguez-
    Valentin and DALR lived in Florida.
    Additionally,     Pennachio          acknowledged         on     cross-
    examination that she did not discount her yearly estimates to
    present value.    Rather, she opined, the cost increases for DALR's
    - 5 -
    medical care and life care over his lifetime would offset any
    applicable discount rate.
    Per a pre-trial ruling on Doctors' Center's motion in
    limine,     the   court   prohibited    Pennachio   (who    lacked   requisite
    expertise) from opining about DALR's life expectancy given his
    medical     condition.1     Ultimately,      neither   Doctors'   Center   nor
    Rodríguez-Valentin presented any expert testimony about DALR's
    life expectancy.
    III.         Jury Instructions and Verdict
    Consistent with the parties' proposed instructions, the
    court instructed the jury that it could award compensatory damages
    to Rodríguez-Valentin and DALR for damages they were "reasonably
    likely to suffer in the future."            It instructed the jury that it
    should be "guided by common sense" in fashioning any award and
    that it could not engage in "arbitrary guesswork." The court added
    that the law does not require proof of the amount of damages "with
    mathematical precision but only with as much definiteness and
    accuracy as the circumstances permit."           It asked the jury to use
    "sound     discretion"    and   to   draw   "reasonable    inferences"   where
    appropriate from the "facts and circumstances in evidence."
    In addition, prior to Pennachio's testimony, the court
    1
    denied a motion by Doctors' Center to limit Pennachio's testimony
    to only one year of expenses.
    - 6 -
    With respect to DALR's life expectancy, Doctors' Center
    did not seek either a ruling from the judge that life expectancy
    must be proved by expert testimony or a suitable modification to
    the court's jury instruction on damages.       Nor did Doctors' Center
    request a special verdict form on DALR’s life expectancy.           In the
    end, Doctors' Center permitted the case to go to the jury without
    making any argument about how the lack of expert testimony on life
    expectancy should impact the jury's calculation of DALR's future
    life care costs.2
    The   jury   found   Doctors'   Center   liable   and   awarded
    $12,996,000 in future life care costs to Rodríguez-Valentin and
    DALR.    The jury awarded an additional $1,300,000 for physical and
    emotional pain and suffering.      The jury apportioned 92 percent of
    that liability to two treating physicians with whom Rodríguez-
    Valentin settled prior to trial.     The jury apportioned to Doctors'
    Center the remaining 8 percent, which sums to $1,143,680.
    2 During closing arguments, Doctors' Center objected to
    Rodríguez-Valentin's observation that there was no evidence
    presented by either side about life expectancy on the ground that
    Rodríguez-Valentin's counsel was improperly "talking about life
    expectancy." The court overruled Doctors' Center's objection.
    - 7 -
    IV.         Post-Verdict Motions
    After the jury's verdict, Doctors' Center renewed3 a
    motion for judgment as a matter of law under Rule 50 and moved for
    a new trial and/or remittitur of the damages award under Rule 59.4
    Doctors' Center argued, as it does on appeal, that Rodríguez-
    Valentin's evidence was insufficient to support the jury's verdict
    as to liability or, alternatively, that the weight of the evidence
    required the jury's verdict to be overturned and a new trial to be
    held.     As to remittitur of the damages award or a new trial on
    damages, Doctors' Center argued that the jury's award for future
    life care costs was speculative because Rodríguez-Valentin failed
    to submit expert testimony about DALR's life expectancy.    Doctors'
    Center also argued that Pennachio's calculations were deficient.
    The district court denied Doctors' Center's motions.   As
    to Doctors' Center's motions for judgment as a matter of law and
    for a new trial on liability, the district court found that Dr.
    Halbridge's testimony supported the jury's verdict.        As to the
    motion for a new trial on damages and/or remittitur, the district
    3As it was required to do to preserve its arguments, Doctors'
    Center moved for judgment as a matter of law for the first time
    before the matter was submitted to the jury. See Fed. R. Civ. P.
    50(a); Santos-Arrieta v. Hospital del Maestro, 
    14 F.4th 1
    , 8 (1st
    Cir. 2021). The district court deferred ruling on the motion, and
    Doctors' Center renewed its motion after the jury's verdict.
    4Doctors' Center filed its three motions together as part of
    one omnibus legal document.
    - 8 -
    court stated that the jury could have determined that DALR's life
    expectancy was 46 years5 by dividing the award for future care
    costs by the amount that Pennachio testified DALR would require
    for care each year.     The district court, however, acknowledged
    that the life expectancy of a child with cerebral palsy "likely
    would be a proper subject for expert testimony."       Nonetheless, the
    district court concluded that the jury in this case could issue an
    award for future costs without expert testimony on life expectancy
    because damages in a negligence action need not be shown with
    mathematical certainty.
    The court also stated that other jurisdictions permit a
    jury to infer life expectancy from testimony about the injured
    person's   medical   condition   and   pain   and   suffering.   While
    acknowledging that "the far better practice would have been for
    both parties to present competent expert testimony of plaintiff's
    life expectancy," the district court found that the jurors could
    make a reasonable estimate of DALR's life expectancy based on their
    common sense, personal knowledge, and experience.         The district
    court also reasoned that the jury heard and rejected Doctors'
    Center's arguments about errors in Pennachio's calculations for
    DALR's future life care costs.
    5 DALR was 10 years old at the time of trial, so, under these
    calculations, he would be expected to live another 36 years.

    DISCUSSION
    Doctors' Center appeals the district court's denial of
    its motions for judgment as a matter of law, for a new trial, and
    for remittitur of the jury's damages award. We address each matter
    in turn, and, in the end, affirm the district court's rulings.
    I.        Judgment as a Matter of Law
    Doctors' Center challenges the district court's denial
    of its renewed motion for judgment as a matter of law under Federal
    Rule of Civil Procedure 50(b).    Doctors' Center contends that the
    district court erred by denying the motion because Doctors' Center
    presented the expert testimony of Drs. de la Vega and Solis, both
    of whom opined, in contention with Dr. Halbridge, that the nurses
    acted appropriately under the circumstances.
    The court reviews de novo the denial of a renewed, post-
    verdict motion for judgment as a matter of law under Rule 50(b).
    See Fresenius Med. Care Holdings, Inc. v. United States, 
    763 F.3d 64
    , 67 (1st Cir. 2014).   "If a party has been fully heard on an
    issue during a jury trial and the court finds that a reasonable
    jury would not have a legally sufficient evidentiary basis to find
    for the party on that issue," the court can order a new trial or
    direct the entry of judgment in the moving party's favor as a
    matter of law.   See Fed. R. Civ. P. 50(a)-(b).      A trial court
    evaluating a motion for judgment as a matter of law under Rule
    50(b) must "view the evidence in the light most flattering to the
    - 10 -
    verdict and must draw all reasonable inferences therefrom in favor
    of the verdict."          Fresenius, 763 F.3d at 67-68.
    Under Puerto Rico law,6 to prove medical malpractice the
    plaintiff must demonstrate, by a preponderance of the evidence, an
    applicable standard of care, that the defendant acted or failed to
    act   in    violation      of   the    applicable    standard   of     care,    and    a
    sufficient      causal     connection      between    the   defendant's        act    or
    failure to act and the plaintiff's injuries.                See Pagés-Ramírez v.
    Ramírez-González, 
    605 F.3d 109
    , 113 (1st Cir. 2010).                    Viewing the
    evidence in the light most favorable to Rodríguez-Valentin, the
    jury's      verdict   finding         Doctors'   Center     liable     for     medical
    malpractice is supported by the evidence.                 The district court did
    not err in denying Doctors' Center's motion for judgment as a
    matter of law.
    Doctors' Center's primary argument is that the district
    court should have given greater weight to the testimony of its
    experts as opposed to that of Dr. Halbridge.                But, as the district
    court      found,   Dr.    Halbridge's     opinion    (i.e.,    that    the     nurses
    breached the applicable standard of care by failing to stop
    administering Pitocin and by failing to inform treating physicians
    that DALR's heart rate variability had decreased) was sufficient
    6The substantive law of Puerto Rico controls in this
    diversity suit.   See Cortés-Irizarry v. Corporación Insular de
    Seguros, 
    111 F.3d 184
    , 189 (1st Cir. 1997).
    - 11 -
    to support the jury's verdict as to those issues.      The jury was
    entitled to credit Dr. Halbridge's testimony over that of Drs. de
    la Vega or Solis.    See Feliciano-Hill v. Principi, 
    439 F.3d 18
    , 26
    (1st Cir. 2006); Lama v. Borras, 
    16 F.3d 473
    , 478 (1st Cir. 1994).
    Doctors' Center also argues that the jury could not find
    liability based on Dr. Halbridge's testimony because he opined
    that the nurses breached a standard of care applicable generally
    in the United States as opposed to a standard of care specific to
    Puerto Rico.    We find no merit to Doctors' Center's argument.   The
    district court instructed the jury that the standard of care in
    this case was "equal to the degree of care exercised by other
    nurses in the same or similar localities."7   Dr. Halbridge, having
    described what the applicable standard of care for the nurses would
    be, added that, as to the nurses in this case, the standard of
    care was the same as the standard of care in the United States
    generally.     For purposes of this case, the jury was entitled to
    credit Dr. Halbridge's opinion that the applicable standards of
    care in Puerto Rico and the rest of the United States are the same.
    See Lama, 
    16 F.3d at 478
    .
    Doctors' Center's other arguments about the sufficiency
    of the evidence are without merit and do not warrant further
    7 Since it is not a matter challenged on appeal, we make no
    ruling about whether the district court's instruction was the
    correct interpretation of Puerto Rico law.
    - 12 -
    discussion.    The district court correctly denied Doctors' Center's
    motion for judgment as a matter of law.
    II.       Motion for a New Trial as to Liability
    Leveraging the same arguments presented in its motion
    for judgment as a matter of law under Rule 50, Doctors' Center
    contends that the district court erred by denying its motion for
    a new trial under Federal Rule of Civil Procedure 59.     Under Rule
    59, "[t]he court may, on motion, grant a new trial on all or some
    of the issues -- and to any party -- . . . after a jury trial, for
    any reason for which a new trial has heretofore been granted in an
    action at law in federal court."    Fed. R. Civ. P. 59(a)(1)(A).   "A
    district court's power to grant a motion for new trial is much
    broader than its power to grant a [Rule 50 motion.]"     Jennings v.
    Jones, 
    587 F.3d 430
    , 436 (1st Cir. 2009).
    A trial judge may grant a new trial if the jury's verdict
    is "against the weight of the evidence" or if "action is required
    in order to prevent injustice."    
    Id. at 436
    .   A district court can
    independently weigh the evidence when evaluating a motion for a
    new trial under Rule 59 and therefore can determine that a witness
    or evidence lacks credibility; in other words, the court need not
    take the evidence in the light most favorable to the nonmoving
    party.   
    Id.
    At the same time, trial judges "do not sit as thirteenth
    jurors, empowered to reject any verdict with which they disagree."
    - 13 -
    
    Id.
       Indeed, when reviewing a denial of a motion for new trial
    that was, at bottom, based on sufficiency of the evidence, the
    standards under Rule 50 and Rule 59 effectively "merge."        See
    Dimanche v. Mass. Bay Transp. Auth., 
    893 F.3d 1
    , 8 n.9 (1st Cir.
    2018).   Moreover, our review of the district court's denial of
    Doctors' Center's motion for a new trial is only for abuse of
    discretion.   Jennings, 
    587 F.3d at 435-37
    .
    Considering    the     deferential    abuse-of-discretion
    standard alongside the reality that Doctors' Center's arguments
    under Rule 59 and Rule 50 are based on the same sufficiency-of-
    the-evidence grounds, we affirm the district court's denial of
    Doctors' Center's motion for a new trial as to its liability.    In
    other words, consideration of the same facts that lead us to affirm
    the district court's denial of the motion as brought under Rule 50
    likewise lead us to affirm as to Rule 59.      Dr. Halbridge was a
    qualified expert witness who testified that Doctors' Center's
    nurses breached the applicable standard of care during Rodríguez-
    Valentin's labor and DALR's birth.     He explained why that breach
    of the standard of care caused or aggravated DALR's injuries.   The
    jury was entitled to credit Dr. Halbridge's testimony over that of
    Doctors' Center's experts.     The district court did not abuse its
    discretion in deferring to the jury's credibility findings.
    Doctors' Center points to no facts that convince us the
    jury's verdict as to liability was against the weight of the
    - 14 -
    evidence or was otherwise unjust.         Indeed, the district court's
    analysis    of    the   evidence   presented   at   trial    was    accurate,
    thoughtful,      and thorough, leaving us      with no      doubt that    the
    decision was within its considerable discretion.            See 
    id. at 441
    .
    III.        Motions for a New Trial on Damages or Remittitur of
    Future Life Care Costs Award
    Lastly, Doctors' Center contends that the district court
    abused its discretion by denying its motion for a new trial or
    remittitur on the ground that the jury's $12,966,000 award for
    DALR's future life care costs was excessive and unsupported by the
    evidence.    Specifically, Doctors' Center argues that the award for
    future care costs should be reduced, or a new trial on damages
    granted, because Rodríguez-Valentin presented no expert testimony
    about DALR's life expectancy and because Pennachio based her
    calculations on erroneous assumptions.
    As with motions for a new trial on liability, appellate
    review for denial of a motion for a new trial on damages or
    remittitur under Rule 59 is for abuse of discretion.               See 
    id. at 435-36
    .     The denial of such a motion "will be reversed only if
    'the jury's verdict exceeds any rational appraisal or estimate of
    the damages that could be based on the evidence before the jury.'"
    Astro-Med, Inc. v. Nihon Kohden Am., Inc., 
    591 F.3d 1
    , 13 (1st
    Cir. 2009) (quoting Smith v. Kmart Corp., 
    177 F.3d 19
    , 29 (1st
    Cir. 1999)).     When evaluating a motion for a new trial on damages,
    - 15 -
    or for remittitur, the court considers the evidence in the light
    most favorable to the prevailing party.          Wortley v. Camplin, 
    333 F.3d 284
    , 297 (1st Cir. 2003).
    Under Rule 59, an award for future life care costs is
    rational   when    it   is   supported   by    the   evidence,   reasonable
    inferences from that evidence, and the jury's common sense, as
    opposed to speculation or conjecture.           See Astro-Med, Inc.,

    Las Islas Municipio,

    , 23-24 (1st Cir. 2014).             And a
    district court does not abuse its discretion by declining to reduce
    a jury's verdict or award a new trial where the grounds for doing
    so derive from the movant's speculation about what the jury might
    have found or what evidence not presented might have demonstrated.
    See Loan Modification Grp., Inc. v. Reed, 
    694 F.3d 145
    , 154 (1st
    Cir. 2012).   Here, the jury's verdict was not beyond "any rational
    appraisal or estimate of the damages that could be based upon the
    evidence before the jury."       See 
    id.
          Doctors' Center's arguments
    fail to convince us otherwise.
    First, Doctors' Center contends that the district court
    abused its discretion by denying its motion under Rule 59 because
    Rodríguez-Valentin did not present expert testimony about DALR's
    life expectancy.    Specifically, Doctors' Center argues that, under
    Puerto Rico law, an award for future care costs is speculative
    unless the plaintiff submits expert testimony about his or her
    - 16 -
    life expectancy.     Given the procedural posture of this case and
    waivers by Doctors' Center, as explained below, we do not reach
    the legal question of whether Puerto Rico law requires such expert
    testimony.
    Doctors' Center did not timely argue to the district
    court that the jury could consider DALR's future care costs only
    by reference to expert testimony.     Similarly, Doctors' Center did
    not timely argue that the jury had to make an estimate of DALR's
    life expectancy, or even that it needed to calculate DALR's future
    care costs in any particular way.     Indeed, Doctors' Center's life
    expectancy argument was not part of its motion for judgment as a
    matter of law.       It was neither reflected in any of Doctors'
    Center's proposed jury instructions nor posed as an objection.
    Likewise, Doctors' Center did not ask for a special verdict form
    that would have required the jury to decide or agree upon DALR's
    life expectancy.
    Instead,    Doctors'   Center   first   argued   that   expert
    testimony on life expectancy was required after the jury delivered
    an adverse verdict, in the context of a motion for a new trial or
    remittitur reviewable only for abuse of discretion.8       Because the
    district court had, without objection, already instructed the jury
    8 In its earlier motion in limine, Doctors' Center argued that
    Pennachio should be precluded from testifying about DALR's life
    expectancy. Doctors' Center did not argue that the jury could not
    award future costs without expert testimony about life expectancy.
    - 17 -
    on how to calculate damages for future life care costs, Doctors'
    Center's argument that the jury could not, as a matter of law,
    return a damages award for future life care costs without expert
    testimony on life expectancy came much too late.
    In other words, Doctors' Center knew before the jury was
    instructed that no expert testimony had been presented on life
    expectancy and that none would be.          Nonetheless, Doctors' Center
    neither moved for judgment as a matter of law on that ground nor
    offered a jury instruction asking the jury to estimate and agree
    on DALR's life expectancy or to calculate that figure in any
    particular way.    See Cheshire Med. Ctr. v. W.R. Grace & Co., 
    49 F.3d 26
    , 35-36 (1st Cir. 1995) (affirming denial of motion for a
    new trial where moving party failed to "object precisely on" the
    pertinent ground and failed to "propose[] to the trial judge an
    acceptable instruction to the jury").         And, Doctors' Center voiced
    no objection to the district court's instruction on calculating
    damages, which was, in short, to award Rodríguez-Valentin "fair
    compensation" of a "reasonable" amount to compensate her and DALR
    for physical, emotional, and economic injuries to whatever extent
    Doctors' Center was legally liable.
    With    no   pertinent   argument    made   by    Doctors'   Center
    before the case was submitted to the jury, the district court's
    jury instructions are the law of the case.                 United States v.
    Oliver, 
    19 F.4th 512
    , 517 (1st Cir. 2021) ("Because the defendant
    - 18 -
    neither objected to the district court's instructions below nor
    assigns error to them on appeal, we treat the instructions as the
    law of the case."); United States v. Kilmartin, 
    944 F.3d 315
    , 328-
    29 (1st Cir. 2019) (holding that an unobjected-to jury instruction
    that is neither patently incorrect nor internally inconsistent
    becomes the law of the case); Moore v. Murphy, 
    47 F.3d 8
    , 11 (1st
    Cir. 1995) ("The failure to object to the instructions at the time,
    and in the manner, designated by Rule 51 is treated as a procedural
    default, with the result that the jury instructions, even if
    erroneous, become the law of that particular case.").
    At best, we can review the district court's instructions
    on this issue for plain error.     See Fed. R. Civ. P. 51(c)-(d)
    (stating when objections to jury instructions must be made and
    that the consequence for failing to timely object to a jury
    instruction is review for "plain error" that "affects substantial
    rights"); Sindi v. El-Moslimany, 
    896 F.3d 1
    , 19-20 (1st Cir. 2018)
    ("It is black-letter law that claims of instructional error not
    seasonably advanced in the district court can be broached on appeal
    only for plain error."); see also P.R. Hosp. Supply, Inc. v. Boston
    Sci. Corp., 
    426 F.3d 503
    , 505 (1st Cir. 2005) ("In general, 'a
    party may not appeal from an error to which he contributed, either
    by failing to object or by affirmatively presenting to the court
    the wrong law.'").   For Doctors' Center to prevail under plain
    error review, we must at least conclude that the claimed error was
    - 19 -
    clear or obvious.         See Sindi, 896 F.3d at 19-20; Babcock v. Gen.
    Motors Corp., 
    299 F.3d 60
    , 65 (1st Cir. 2002).9
    We    cannot    do     so   here.      Doctors'     Center   offers   no
    authority demonstrating that it is clearly the case under Puerto
    Rico law that a plaintiff must present expert testimony about life
    expectancy to receive damages for future care costs in a medical
    malpractice action.          Although we agree with the district court
    that presenting expert testimony about life expectancy is the best
    practice in a medical malpractice case involving an uncommon and
    severe medical condition and a request for future costs, we can
    find no authority clearly establishing that such expert testimony
    is necessary to recover damages for future care costs as a matter
    of   law   in    Puerto    Rico.        Rather,    the   only   arguably   relevant
    authorities offered here are the Puerto Rico Supreme Court cases
    relied on by the district court in denying Doctors' Center's
    motion, Zambrana v. Hospital Santo Asilo de Damas, 
    9 P.R. Offic. Trans. 687
    , 692 (1980), and Suro v. E.L.A, 
    111 P.R. Dec. 456
    , 461
    (1981), which merely stand for the general principle that damages
    need not be computed with mathematical rigor or precision.
    9As we conclude that there was no clear or obvious error, we
    need not reach the other aspects of plain error, which include
    whether the claimed error affected the appellant's substantial
    rights and "seriously impaired the fairness, integrity, or public
    reputation of judicial proceedings." Fothergill v. United States,
    
    566 F.3d 248
    , 251-52 (1st Cir. 2009).
    - 20 -
    Thus, if there were any error under Puerto Rico law in
    the district court's instructions on how to calculate damages, it
    was not plain.   See Sindi, 896 F.3d at 19-20; Babcock, 
    299 F.3d at 65
    .   Considering   those   instructions,   the   evidence   that   was
    presented, and Doctors' Center's failure to timely raise its legal
    argument on the need for expert testimony on life expectancy, the
    district court did not abuse its discretion in denying the motion.
    Finally, Doctors' Center takes issue with Pennachio's
    opinion about DALR's future life care costs because Pennachio did
    not discount her calculations to present value, used numbers based
    on costs in Massachusetts instead of Florida, and did not offset
    her calculations for possible contributions by insurers or the
    government.   The jury, however, heard extensive evidence about
    DALR's condition and the care that he required. The district court
    allowed Doctors' Center substantial leeway in cross-examining
    Pennachio about the accuracy of her calculations.10           Doctors'
    Center's cross-examination of Pennachio included questions about
    whether she discounted her numbers to present value, whether she
    used accurate regional cost-of-living expenses, and whether she
    considered potential offsetting contributions.         And   Pennachio
    10On appeal, Doctors' Center challenges the methodology of
    Pennachio's opinions and does so only in the context of a new trial
    or remittitur, as opposed to admissibility under the Federal Rules
    of Evidence.    Doctors' Center does not challenge Pennachio's
    expertise.
    - 21 -
    explained, as one example, that her methodology did not require
    discounting her numbers to present value because the prospect of
    inflation offset the discount rate.             The jury was therefore able
    to   assess    Pennachio's    testimony,     including      Doctors'   Center's
    criticisms of her methodology, in fashioning its damages award.
    See Casco, Inc. v. John Deere Constr. & Forestry Co., 
    990 F.3d 1
    ,
    13-14 (1st Cir. 2021) (rejecting argument that a new trial or
    remittitur was necessary due to claimed methodological errors by
    plaintiff's damages expert).
    Doctors' Center's other arguments regarding the jury's
    damages award -- including its contention that the damages are
    excessive in light of comparable cases -- are unpersuasive and do
    not merit discussion.
    At   bottom,   the   jury's   verdict   was    not   beyond   "any
    rational appraisal or estimate of the damages that could be based
    upon the evidence before the jury."              Accordingly, the district
    court did not abuse its discretion in denying Doctors' Center's
    motion for a new trial and, in the alternative, remittitur.
    CONCLUSION
    In sum, the district court did not err or abuse its
    discretion in deferring to the jury's evaluation of the evidence.
    Accordingly, the district court's order denying Doctors' Center's
    motions for judgment as a matter of law, for a new trial, or for
    remittitur is affirmed.
