    Before: GARLAND, Chief Judge, TATEL, Circuit Judge, and
    SENTELLE, Senior Circuit Judge.
    Opinion for the Court filed by Circuit Judge TATEL.
    Dissenting opinion filed by Senior Circuit Judge
    SENTELLE.
    TATEL, Circuit Judge: When plaintiffs prevail in a civil
    rights case, the law usually entitles them to recover reasonable
    attorney’s fees. Federal district judges, whom Congress has
    tasked with tabulating those fees, frequently find themselves
    whipsawed between two seemingly discordant instructions:
    (1) ascertain the hourly rate for lawyers performing similar
    work “with a fair degree of accuracy” using “specific
    evidence,” National Association of Concerned Veterans v.
    Secretary of Defense, 
    675 F.2d 1319
    , 1325 (D.C. Cir. 1982),
    but (2) do so without turning fee calculations into “a second
    major litigation,” Hensley v. Eckerhart, 
    461 U.S. 424
    , 437
    (1983). To reconcile those directives, district courts often turn
    to a fee matrix—that is, a chart averaging rates for attorneys at
    different experience levels. For decades, courts in this circuit
    have relied on some version of what is known as the Laffey
    matrix. Created in the 1980s, that matrix is based on a relatively
    small sample of rates charged by sophisticated federal-court
    practitioners in the District of Columbia. Litigants have
    updated the matrix for inflation using an assortment of tools.
    Recently, however, the United States Attorney’s Office sought
    to replace this standby with a new default matrix based on data
    3
    for all types of lawyers—not just those who litigate complex
    federal cases—from the entire metropolitan area—not just the
    District of Columbia.
    In this case, after plaintiffs prevailed in a long-running
    Individuals with Disabilities Education Act class action, the
    district court accepted the District of Columbia’s invitation to
    rely on the USAO’s new matrix in awarding fees. But as we
    explain below, the new matrix departs from the statutory
    requirement that reasonable fees be tethered to “rates
    prevailing in the community” for the “kind and quality of
    services furnished.” 
    20 U.S.C. § 1415
    (i)(3)(C). We therefore
    vacate the award and remand for the district court to recalculate
    the hourly rate based on evidence that focuses on fees for
    attorneys practicing complex federal litigation in the District of
    Columbia.
    I.
    We begin by reviewing the elementary principles
    governing fee-shifting rate calculations and the genealogy of
    fee matrices in this circuit, and then turn to the history of this
    particular case.
    A.
    As Congress enacted a growing number of laws securing
    civil rights, it confronted a problem: “enforcement would prove
    difficult” without private lawsuits, and would-be plaintiffs
    needed skilled lawyers to guide them through the obstacle
    course of complex litigation. Newman v. Piggie Park
    Enterprises, Inc., 
    390 U.S. 400
    , 401 (1968). But those plaintiffs
    often lacked financial resources “indispensable” to attracting
    “competent counsel” willing and able to take on defendants of
    greater means. Save Our Cumberland Mountains, Inc. v.
    Hodel, 
    857 F.2d 1516
    , 1521 (D.C. Cir. 1988) (en banc)
    (internal quotation marks and emphasis omitted). So Congress
    4
    turned      to   fee-shifting      provisions,     simultaneously
    “encourag[ing] plaintiffs to bring suit” and allowing those who
    prevail to finance the cost of legal assistance by recovering fees
    from the defendant. Mary Frances Derfner & Arthur D. Wolf,
    1 Court Awarded Attorney Fees ¶ 5.03, § 7(a) (2018 ed.);
    accord Piggie Park, 
    390 U.S. at 402
     (“Congress therefore
    enacted the provision for counsel fees . . . to encourage
    individuals injured . . . to seek judicial relief . . . .”). “[O]ver
    100 separate statutes” now provide “for the award of attorney’s
    fees.” In re Donovan, 
    877 F.2d 982
    , 991 (D.C. Cir. 1989)
    (internal quotation marks omitted); see also Congressional
    Research Service, Report 94-970, Awards of Attorneys’ Fees
    by Federal Courts and Federal Agencies 57–117 (Oct. 22,
    2009) (listing them).
    The basic formula for calculating an attorney fee award
    seems straightforward: multiply “the number of hours
    reasonably exp[e]nded in litigation” by “a reasonable hourly
    rate or ‘lodestar.’” Cumberland Mountains, 
    857 F.2d at 1517
    .
    The Supreme Court has offered guidance about how to perform
    that calculation, explaining that “reasonable fees” are those
    grounded in rates “prevailing in the community for similar
    services by lawyers of reasonably comparable skill, experience
    and reputation.” Blum v. Stenson, 
    465 U.S. 886
    , 895 n.11
    (1984). The statute at issue here, the Individuals with
    Disabilities Education Act (IDEA), codifies that interpretation
    of “reasonable”: “Fees awarded under [IDEA] shall be based
    on rates prevailing in the community in which the action or
    proceeding arose for the kind and quality of services
    furnished.” 
    20 U.S.C. § 1415
    (i)(3)(C).
    Implementing this relatively simple definition has proven
    vexing. See Reed v. District of Columbia, 
    843 F.3d 517
    , 521
    (D.C. Cir. 2016) (“[D]etermining . . . the prevailing market
    rate[] is ‘inherently difficult.’” (quoting Eley v. District of
    5
    Columbia, 
    793 F.3d 97
    , 100 (D.C. Cir. 2015))). We have
    operationalized it with a burden-shifting framework: To begin,
    “a fee applicant bears the burden of establishing entitlement to
    an award . . . and justifying the reasonableness of the rates.”
    Covington v. District of Columbia, 
    57 F.3d 1101
    , 1107 (D.C.
    Cir. 1995). At that point, the claimed fee “is presumed to be the
    reasonable fee contemplated by” the statute, and the burden
    shifts to the defendant to present “equally specific
    countervailing evidence” if it seeks a different (presumably
    lower) rate. 
    Id. at 1109
     (internal quotation marks omitted).
    For either party, a matrix showing the average hourly price
    tag of comparable lawyers may “provide a useful starting
    point” in calculating market rates. 
    Id.
     But because such
    “matrices are somewhat crude,” the matrix’s proponent usually
    cannot stop there. 
    Id.
     Instead, the proponent may point to
    additional evidence, which can include “surveys to update the
    matrix; affidavits reciting the precise fees that attorneys with
    similar qualifications have received from fee-paying clients in
    comparable cases; and evidence of recent fees awarded by the
    courts or through settlement to attorneys with comparable
    qualifications handling similar cases.” 
    Id.
     No particular type of
    evidence can be considered gospel; “evidence of the prevailing
    market rate can take many forms.” Eley, 793 F.3d at 104 n.5.
    The first and most influential matrix in this circuit debuted
    in Laffey v. Northwest Airlines, Inc., a 1983 Title VII and Equal
    Pay Act case. 
    572 F. Supp. 354
     (D.D.C. 1983), affirmed in part,
    reversed in part, 
    746 F.2d 4
     (D.C. Cir. 1984), overruled in part,
    Cumberland Mountains, 
    857 F.2d 1516
    . In those fledgling
    days—before big data, Google, or a prolific cottage industry
    dedicated to studying the legal profession—the prevailing
    plaintiff’s attorney created a fee schedule by “inquir[ing] into
    the billing rates of firms in Washington, D.C., which [were]
    engaged in active litigation practice in the federal courts” and
    6
    collecting “affidavits . . . giving specific rate information,
    supporting and substantiating the rates described.” First
    Rezneck Affidavit ¶ 9, Laffey v. Northwest Airlines, Inc., No.
    1:70-cv-02111-AER (D.D.C. Mar. 17, 1983), Joint Appendix
    (“J.A.”) 571–72. A star was born. See Eley, 793 F.3d at 100
    (describing the Laffey matrix as “[t]he most commonly used fee
    matrix” in this circuit “for lawyers who practice ‘complex
    federal litigation’”).
    We endorsed the Laffey matrix in Save Our Cumberland
    Mountains, Inc. v. Hodel. Sitting en banc, we “commend[ed]
    its use for the year to which it applie[d]” and suggested “the
    compiling of a similar schedule of prevailing community rates
    for other relevant years.” Cumberland Mountains, 
    857 F.2d at 1525
    . Joseph Yablonski, a Washington, D.C. litigator,
    answered that call by speaking “with attorneys from” seven
    major law firms and comparing the rates he “found with the
    rates set forth in two broad-ranging surveys of hourly rates
    published in the National Law Journal.” Yablonski
    Declaration ¶¶ 5–6, Broderick v. Ruder, No. 1:86-cv-01834-
    JHP (D.D.C. 1989), J.A. 624–25. Yablonski’s labors updated
    Laffey’s rates through 1989. Somewhat confusingly, litigants
    routinely refer to both the original 1983 matrix and Yablonski’s
    1989 update as the “Laffey matrix.”
    In the following decades, hourly rate disputes in this
    circuit often revolved around whether a case was sufficiently
    complex to warrant Laffey rates, see, e.g., Reed, 843 F.3d at
    525–26 (addressing that question in an IDEA case), and, if so,
    how best to update the Laffey matrix for inflation, see Eley, 793
    F.3d at 101 (describing that debate). The USAO maintained
    one version of the matrix, relying on the original 1983 base data
    updated through a Bureau of Labor Statistics inflation index
    that tracks regional price increases in all goods. Id. Some
    plaintiffs’ attorneys argued that this index failed to capture the
    7
    true rate of inflationary change and began advancing a version
    of the 1989 Laffey data updated with a different Bureau of
    Labor Statistics index called the Legal Services Index (LSI),
    which estimates price increases for the legal market
    nationwide. Id. at 101–02. When the two were pitted against
    each other, courts frequently found the LSI Laffey matrix more
    persuasive. See id. (observing that “critics” of the USAO’s
    Laffey matrix had “advocated, to some degree of success, for a
    competing Laffey Matrix . . . that uses the Legal Services
    Index”); see also Salazar v. District of Columbia, 
    809 F.3d 58
    ,
    65 (D.C. Cir. 2015) (affirming district court’s choice to apply
    the LSI Laffey matrix over the USAO’s).
    Since 2015, however, the USAO has undertaken a major
    effort to replace the Laffey datasets by using a more current rate
    survey as the base for a brand new matrix. For those figures,
    the USAO turned to the annual Survey of Law Firm
    Economics, published by ALM Legal Intelligence (“ALM”) in
    conjunction with the National Law Journal. The off-the-rack
    version of that survey publishes hourly rate data for thousands
    of lawyers engaged in all types of practice, all over the country.
    The USAO custom ordered a subset of the 2011 survey’s data
    covering the “Washington, D.C. metro area,” defined by the
    Census Bureau to include portions of Virginia, Maryland, and
    West Virginia. Plaintiffs’ Exhibit 84, DL v. District of
    Columbia, 1:05-cv-01437-RCL, ECF No. 566-17 (D.D.C. May
    21, 2017), J.A. 1573. This tailored dataset summarizes
    “standard hourly billing rates” for 350 attorneys, yielding
    average rates hundreds of dollars below those reflected in the
    LSI Laffey matrix. 
    Id.
     The USAO intends to update ALM’s
    2011 data for inflation using still another index focusing on
    industry-specific price increases nationwide.
    B.
    This case began almost fifteen years ago when plaintiffs,
    8
    parents of several children aged three to six, filed suit “alleging
    a ‘pervasive and systemic’ breakdown in the” District of
    Columbia’s compliance with IDEA resulting from the
    District’s failure “to identify large numbers of disabled
    children and delivering inadequate and delayed [educational]
    services to many others.” DL v. District of Columbia, 
    860 F.3d 713
    , 718 (D.C. Cir. 2017). Following a protracted dispute
    regarding class certification resulting in two separate trips to
    this court, extensive motions practice, and two separate bench
    trials, “the district court issued a 130-page opinion finding the
    District liable” on most counts and ordered sweeping injunctive
    relief. 
    Id.
     at 719–20. We affirmed “in all respects.” 
    Id. at 717
    .
    As plaintiffs had prevailed on the majority of their claims,
    fee litigation commenced. Although the parties contested many
    issues in the district court, all but the hourly rate have dropped
    out on appeal. Plaintiffs sought attorney fees based on the LSI
    version of the Laffey matrix. The District offered the new
    USAO matrix as an alternative. Both sides produced a pile of
    evidence purporting to prove that their matrix better reflects the
    relevant rates, including affidavits from economists and
    attorneys; various commercially-available rate surveys; and
    information regarding fees requested, awarded, and settled on
    in other cases.
    The district court began by finding that both matrices were
    “presumptively” applicable to “complex federal litigation.” DL
    v. District of Columbia, 
    267 F. Supp. 3d 55
    , 69 (D.D.C. 2017).
    Comparing the two, however, the court was more persuaded by
    the USAO’s new matrix, especially its statistically significant
    sample size and “more narrowly defined” experience
    categories. 
    Id.
     at 69–70. Thus, despite plaintiffs’ objection that
    the data underlying the USAO’s new matrix incorporates rates
    for non-litigators outside the District, the court ordered
    plaintiffs to recalculate their fees using the USAO’s rates. 
    Id.
    9
    at 72. Largely as a result of that order (in conjunction with a
    few minor adjustments unchallenged on appeal), the requested
    $9.76 million fee dropped to a $6.96 million award. Plaintiffs
    appeal.
    II.
    Simply stated, the question before us is whether the district
    court abused its discretion in determining that the hourly rates
    in the USAO’s matrix are “reasonable.” Recall that IDEA
    makes express a requirement that inheres in any statutory
    provision for “reasonable attorney’s fees”: such fees must be
    calculated using “rates prevailing in the community in which
    the action or proceeding arose for the kind and quality of
    services furnished.” 
    20 U.S.C. § 1415
    (i)(3)(C); accord Blum,
    
    465 U.S. at
    895 n.11 (explaining that this is part of what it
    means to be “reasonable”). Recall also that once “a fee
    applicant” has met the preliminary burden of “justifying the
    reasonableness of the rates,” those rates are “presumed to
    be . . . reasonable” unless and until the defendant offers
    “equally specific countervailing evidence” supporting another
    rate. Covington, 
    57 F.3d at 1107, 1109
     (internal quotation
    marks omitted). We will reverse a district court’s determination
    that certain hourly rates are reasonable when there has been a
    “clear misapplication of legal principles, arbitrary fact finding,
    or unprincipled disregard for the record evidence.” Kattan ex
    rel. Thomas v. District of Columbia, 
    995 F.2d 274
    , 278 (D.C.
    Cir. 1993), as amended (June 30, 1993); see also Koon v.
    United States, 
    518 U.S. 81
    , 100 (1996) (“A district court by
    definition abuses its discretion when it makes an error of
    law.”).
    A.
    We begin with the District’s argument that plaintiffs failed
    to meet their initial burden to support with specific evidence
    10
    their claim that the LSI Laffey rates satisfy the statute’s
    command. Our recent opinion in Salazar v. District of
    Columbia, however, all but compels the conclusion that
    plaintiffs cleared that bar. The Salazar plaintiffs relied on the
    same types of evidence in essentially the same level of detail to
    support the same rate matrix (for a slightly earlier year). 809
    F.3d at 64–65. That evidence, we concluded, was more than
    enough to pass the burden onto the District. Id. at 65 (“With
    these numbers and submissions in the record, the district
    court’s point that the LSI-adjusted matrix is probably a
    conservative estimate of the actual cost of legal services in this
    area, does not appear illogical.” (internal quotation marks
    omitted)). The District has given us no reason to reach a
    different conclusion on such a similar record.
    B.
    The meatier question, then, is whether the District satisfied
    its rebuttal burden. The USAO’s new matrix formed the
    cornerstone of the rebuttal case, and the district court treated
    that matrix as “presumptively” applicable. DL, 267 F. Supp. 3d
    at 69. We are at a loss to understand the basis of that
    presumption, given that this court had yet to review the new
    matrix. The proper inquiry, under the applicable legal
    principles, was whether the District supported its matrix with
    “equally specific countervailing evidence.” Covington, 
    57 F.3d at 1109
     (internal quotation marks omitted).
    The District contends that the USAO’s more recent raw
    data and statistically significant sample size make its matrix
    superior to plaintiffs’ favored LSI Laffey matrix. Crucially,
    however, those traits matter only if the data surveys the
    relevant population. As plaintiffs’ expert, Dr. Michael
    Kavanaugh, put it, “comparable prices are found by observing
    comparable goods.” Second Kavanaugh Declaration ¶ 8, DL v.
    District of Columbia, 1:05-cv-01437-RCL, ECF No. 566-11
    11
    (Apr. 26, 2017), J.A. 1380. For example, for someone house
    hunting in Memphis, a survey of real estate prices in Seattle—
    even one with a perfect response rate updated daily—would be
    of no use. The same is true here. The USAO’s matrix is helpful
    only if it canvasses the relevant type of lawyer, which it does
    not.
    To begin with, the USAO’s matrix incorporates rates for
    the wrong types of practitioner. The parties and the district
    court agree that this case qualifies as “complex federal
    litigation.” DL, 267 F. Supp. 3d at 69. Yet rather than confine
    its data to rates charged by attorneys practicing that genre of
    litigation—or even just litigators in general—the survey that
    the USAO drew from incorporates rates from all types of
    lawyers. Respondents include real estate lawyers, family
    lawyers, and insurance lawyers—lawyers manifestly not
    offering “the kind and quality of services furnished” by these
    plaintiffs’ attorneys, as the statute requires of comparators. 
    20 U.S.C. § 1415
    (i)(3)(C); accord Eley, 793 F.3d at 105 (fee
    analysis should focus on “lawyers . . . doing the same type of
    litigation” (emphasis omitted)). It is obvious that the rates
    charged for, say, simple wills are lower than those for complex
    federal litigation. Worse still, nothing in the record reveals
    what percentage of respondents in the USAO’s custom cross-
    section of the ALM data were litigators. For all we know, the
    number could be anywhere from zero to all 350.
    Compounding this first error, the USAO’s custom-ordered
    dataset surveys lawyers far beyond the “community in which
    th[is] action . . . arose.” 
    20 U.S.C. § 1415
    (i)(C)(3). Plaintiffs
    brought this case on behalf of District of Columbia residents
    regarding District of Columbia schools against the District of
    Columbia. Yet the USAO matrix draws from lawyers who
    practice in the entire “metro area” as defined by the United
    States Census Bureau. The phrase “metro area” suggests
    12
    proximity, but—according to the Census Bureau’s definition—
    that area stretches well beyond the District to cover thousands
    of square miles over three states, from rural Madison County,
    Virginia, to the eastern shore of Maryland, back to the foothills
    of Jefferson County, West Virginia. Needless to say, this case
    has no connection to most of those areas. Our court has held
    that ordinarily “the relevant community is the one in which the
    district court sits.” Donnell v. United States, 
    682 F.2d 240
    , 251
    (D.C. Cir. 1982). Accordingly, our decisions refer to the
    relevant community as the District of Columbia. See, e.g.,
    Salazar, 809 F.3d at 64 (discussing “prices for legal services in
    Washington, D.C.”); Covington, 
    57 F.3d at 1104
     (discussing
    evidence of rates “in the District of Columbia”). That general
    rule fits comfortably with the facts of this case. Yet here, more
    than half the data in the USAO’s customized dataset comes
    from outside the District of Columbia, see Appellant’s Br. 20,
    and District counsel acknowledges that it includes data from
    throughout the three neighboring states, see Oral Arg. Rec.
    28:04–28:22. Again, it is obvious, as District counsel
    recognizes, that fees are lower in rural areas than in the District.
    See Oral Arg. Rec. 31:04–31:30. Indeed, the District’s own
    evidence shows that rates for legal services in the District of
    Columbia are among the highest anywhere. National Law
    Journal & ALM Legal Intelligence, The Survey of Law Firm
    Economics, 139–41 (2011 ed.), J.A. 1485–87.
    Confronted with these two flaws, the district court said
    nothing about them, resting exclusively on its statement that
    the USAO’s matrix was “presumptively applicable.” DL, 267
    F. Supp. 3d at 69. In doing so, the court abused its discretion
    twice over. First, by failing to determine whether the USAO’s
    matrix satisfies Congress’s statutory baseline, the court
    committed a “clear misapplication of legal principles.” Kattan,
    
    995 F.2d at 278
    ; see also Koon, 
    518 U.S. at 100
    . And second,
    13
    it “disregard[ed] . . . record evidence” that its chosen matrix
    failed to achieve that baseline. Kattan, 
    995 F.2d at 278
    .
    Calling in reinforcements, the District points to a growing
    consensus among the district judges in this circuit that the
    USAO matrix is superior to Laffey. See, e.g., Lewis v. District
    of Columbia, No. 1:15-cv-521-JEB, 
    2018 WL 6308722
    , at *8
    (D.D.C. Dec. 3, 2018) (collecting cases). Many of those cases
    repeat the district court’s fundamental error here: none finds,
    based on record evidence, that the new matrix is based on rates
    for complex federal litigators in the District. See 
    id. at *9
     (no

    new USAO matrix as “measur[ing] rates in the legal services
    industry”). Others apparently lacked the benefit of any briefing
    on the new matrix’s flaws. See, e.g., Wadelton v. Department
    of State, No. 1:13-cv-412-TSC, 
    2018 WL 4705793

    “no analysis of the USAO’s newest methodology”). So, even
    sympathizing with the district court’s appetite for more recent
    data, we are unpersuaded by its decision to embrace newer but
    irrelevant figures.
    14
    Despite the evidentiary defects in the record, the District
    offers an alternative basis for affirming: its supplemental proof
    demonstrates that the USAO’s matrix accurately reflects
    complex litigation rates in the District of Columbia. But the
    district court made no findings about the evidence the District
    uses to back up that claim, and some of that data appears to be
    of dubious value. For example, the District’s primary redoubt
    comprises two sets of nationwide data from the 2014 ALM
    survey. But it is not at all obvious that these nationwide datasets
    are useful comparators for rates in the District. See National
    Law Journal & ALM Legal Intelligence, The Survey of Law
    Firm Economics 139–41 (2011 ed.), J.A. 1485–87 (showing
    that rates in the District substantially exceed those in most other
    jurisdictions). Nonetheless, mindful of the district court’s
    primary factfinding role, we leave it for that court to assess on
    remand the impact, if any, of the District’s remaining market
    evidence and to take further evidence if necessary to arrive at a
    “reasonable rate.”
    C.
    The District argues that “even if” we reject the USAO’s
    new matrix—as we now have—“that does not mean that
    [plaintiffs] were entitled to rates under the LSI [Laffey]
    Matrix.” Appellee’s Br. 25. But it offers one and only one
    argument for rates in between the two: that this court has held
    that attorneys in IDEA cases should not be compensated at
    Laffey rates. 
    Id.
     That argument mischaracterizes our precedent.
    True, we have held that IDEA cases sometimes fall within a
    submarket characterized by below-Laffey rates. Reed, 843 F.3d
    at 525. But such cases involved individual IDEA plaintiffs
    litigating non-complex cases primarily before an
    administrative body. See id. (noting individual “IDEA litigants
    may not have discovery and pre-trial exchanges of the sort
    found in other federal litigation”); Eley, 793 F.3d at 105 n.6
    (discussing “representation in IDEA administrative due
    15
    process hearings” (internal quotation marks omitted)); accord
    Second Kohn Affidavit ¶¶ 9–17, No. 1:05-cv-01437-RCL,
    ECF No. 566-5 (D.D.C. Apr. 27, 2017), J.A. 1359–61
    (describing typical IDEA case and noting that, “in an even
    unusually complex individual IDEA case appealed to the
    district court,” the “full record . . . would typically fit into two
    banker’s boxes”). Indeed, we have always left open “the
    possibility that . . . fee applicants may be able to demonstrate
    that IDEA cases are ‘complex federal litigation’ to which the
    Laffey Matrix presumptively applies.” Reed, 843 F.3d at 525.
    And here the district court found that this case qualifies as
    “complex federal litigation,” DL, 267 F. Supp. 3d at 69, a
    finding the District has not challenged, see Appellee’s Br. 22
    n.8. It therefore may not claim that fees from individualized
    IDEA actions are appropriate comparators.
    To be sure, the district court identified other concerns
    regarding the LSI Laffey matrix, including (1) the age of the
    raw data; (2) whether it captures a truly representative sample
    of complex federal litigators; and (3) the grouping of attorneys
    into just five experience bands. DL, 267 F. Supp. 3d at 69–70.
    These observations suggest that as time passes, the Laffey
    matrix may well—like shoulder pads, eight-tracks, and other
    ’80s fads before it—be losing its shine. In this particular case,
    however, the District raised no argument that these issues
    justify rates somewhere between the two matrices. See
    Appellee’s Br. 25. Therefore, it has forfeited any such
    contention. Al-Tamimi v. Adelson, 
    916 F.3d 1
    , 6 (D.C. Cir.
    2019) (“A party forfeits an argument by failing to raise it in his
    opening brief.”).
    D.
    One last issue remains: the rates for plaintiffs’ only lawyer
    who regularly bills fee-paying clients, Cyrus Mehri. We see no
    reason why the rates that apply to the rest of plaintiffs’ lawyers
    16
    would yield inadequate compensation for Mehri’s services.
    Plaintiffs contend that Mehri is instead entitled to his usual
    billing rate, but his sparse affidavit tells little about whether his
    relatively minimal contributions to the case differ sufficiently
    from his colleagues’ to warrant a different methodology. Mehri
    Affidavit, No. 1:05-cv-01437-RCL, ECF No. 537-17 (Sept. 26,
    2016), J.A. 428–29 (asserting he “did work related to class
    certification” and tried to “broker a resolution to this case”). As
    Eley instructs, the focus is properly on the market rate “charged
    by for-profit lawyers” for “the same type of litigation.” 793
    F.3d at 105. And although stating in his affidavit that he
    charges the same rate no matter what type of work he performs,
    Mehri nowhere represents that a client on the market would
    hire him at that rate for the types of services he performed in
    this case. Accordingly, the district court did not abuse its
    discretion by compensating Mehri using the same method as
    his co-counsel.
    III.
    Not so long ago, the prevailing belief was that parties
    would often be able to agree on reasonable attorney’s fees. See
    Hensley, 
    461 U.S. at 437
     (“Ideally, of course, litigants will
    settle the amount of a fee.”). We regret that this prophecy has
    gone unfulfilled and fervently hope that practitioners in this
    circuit—on both the plaintiff and defense sides of the bar—will
    work together and think creatively about how to produce a
    reliable assessment of fees charged for complex federal
    litigation in the District. In the meantime, however, we must
    discharge our duty to ensure that the adversarial alternative
    produces results that respect Congress’s mandates. Because the
    fee award in this case falls short of that goal, we vacate it and
    remand for further proceedings consistent with this opinion.
    So ordered.
    SENTELLE, Senior Circuit Judge, dissenting: Ambrose
    Bierce defined a lawyer as “[o]ne skilled in circumvention of the
    law.” Ambrose Bierce, The Unabridged Devil’s Dictionary 147
    (Univ. of Georgia Press 2000). Though I do not suggest that this
    is an accurate description, I nonetheless would observe that the
    jurisprudence of IDEA litigation attorney-fee awards well
    establishes that lawyers and jurists are professionals skilled in
    complicating the law. The jurisprudential odyssey on this sea
    began with a rather straightforward mandate from Congress in
    
    20 U.S.C. § 1415
    (i)(3), a subsection headed “Jurisdiction of
    district courts; attorney fees.” (Emphasis added.)
    More specifically, Congress provided that, “[i]n any action
    or proceeding brought [under the IDEA provision providing
    judicial relief], the court, in its discretion, may award reasonable
    attorneys’ fees as part of the costs.”                   
    20 U.S.C. § 1415
    (i)(3)(B)(i). While the following subsections provide
    some limitations and directions for the computation of the
    award, the basic task created by Congress and placed within the
    jurisdiction of the district court is a factual determination of the
    reasonableness of attorneys’ fees to be awarded as part of the
    costs in IDEA actions. The congressional language would seem
    to rather straightforwardly call for findings of fact, concerning
    the reasonableness of attorneys’ fees to be awarded. The district
    court in the present controversy made such findings which we
    are now called upon to review.
    “[T]he standard governing appellate review of a district
    court’s finding of [facts] is that set forth in Federal Rule of Civil
    Procedure 52(a).” Anderson v. Bessemer City, 
    470 U.S. 564
    ,
    573 (1985). Rule 52(a) provides that “[f]indings of fact,
    whether based on oral or other evidence, must not be set aside
    unless clearly erroneous . . . .” Not only would it seem apparent
    that this is the standard of review we should be applying to the
    issues before us, it seems especially appropriate where the
    question is expressly described as within the “jurisdiction of
    2
    district courts” in the enactment creating the right to such a
    finding. 
    20 U.S.C. § 1415
    (i)(3).
    Indeed, we have expressly held in previous IDEA class
    litigation that “[w]e review the district court’s fee award for
    abuse of discretion, and will not upset its hourly rate
    determination absent clear misapplication of legal principles,
    arbitrary factfinding, or unprincipled disregard for the record
    evidence.” Eley v. District of Columbia, 
    793 F.3d 97
    , 103 (D.C.
    Cir. 2015) (emphasis added) (internal quotation marks and
    citations deleted). In spite of this standard, in the present case,
    the majority reviews the district court’s determination of the
    factual questions before us, not for compliance with Rule 52(a),
    nor for abuse of discretion, but as if it were a question of law.
    The majority asks not whether the district court committed
    a clear misapplication of legal principles, or arbitrary
    factfinding, or unprincipled disregard for record evidence, but
    rather whether the district court’s findings of fact fit within a
    detailed grid, the Laffey Matrix, which might be construed as a
    proffer by the prevailing party for findings of fact, but more
    closely resembles a detailed regulation adopted by some
    government agency after an appropriate period of notice and
    comment.
    The district court found another matrix to be more factually
    appropriate. The making of that factual determination, under the
    law in general and under the governing statute in particular, is
    the district court’s province. I grant that we as an appellate
    reviewing court have participated in the establishment of this
    legislation-like matrix. I further realize that we have the
    authority to establish precedent binding upon district courts and
    upon panels of this court such as this one. LaShawn A. v. Barry,
    
    87 F.3d 1389
    , 1395 (D.C. Cir. 1996) (en banc). Nonetheless, I
    3
    have always understood our authority to make binding
    precedents to govern matters of law, not findings of fact. The
    present controversy concerns a matter of fact. This, under the
    binding precedent of both this circuit and the Supreme Court and
    the Rules of Civil Procedure is within the discretion of the
    district court, subject only to the limited review described above.
    While not necessary to my dissent, I further note that
    appellants proffered nothing to convince me that the LSI Matrix
    preferred by them is inherently more appropriate for the findings
    required by the district court in this case than the USAO Matrix
    relied upon in the district court’s findings. Appellants’
    argument rests on the proposition that the award should have
    been based on fees determined by survey of a specific
    subcategory of attorneys out of the several set forth in their
    preferred matrix: specifically, practitioners in complex federal
    litigation in Washington, D.C. The matrix employed by the
    district court instead considered the rates of a broader sampling
    of attorneys from a broader geographic area, including not only
    the District of Columbia, but also adjacent portions of three
    states. It is not apparent how this was an abuse of discretion of
    the sort that would make the court’s determination reversible
    under the standard set forth in the rules and blessed in Anderson
    v. Bessemer City, and a multitude of other cases.
    Appellants seem to argue that the district court’s
    determination was inconsistent with Congress’s instructions in
    section 1415(i)(3)(C). That section mandates that an IDEA fee
    award “shall be based on rates prevailing in the community in
    which the action or proceeding arose for the kind and quality of
    services furnished.” It does not mandate that the community
    should be limited to a “community” defined as only the largest
    municipality in a region, or to the highest priced professional
    practicing in that limited community.
    4
    As the purpose of Congress in setting forth the general
    limitations of subsection (C) appears to encourage the
    determination of a market for assessing the reasonableness of
    fees, it would seem that an analysis of the fitness of either
    matrix to that determination could, without violating the
    standard under which we review factfinding, include reflecting
    on the reasonableness of persons obtaining legal representation
    in such a hypothetical market. It might be that those persons
    would choose the most expensive professionals for the most
    expensive part of the market. While such conduct might not be
    unreasonable, neither is it inherently unreasonable that they
    might choose a less imposing or less expensive attorney who is
    nonetheless trusted and competent to do the work in the case. It
    may shock counsel before us to learn, but it is not necessary in
    every case to have the most specialized or the most expensive
    counsel in order to receive competent legal services. In any
    event, it is not arbitrary fact finding for the judge to conduct an
    analysis of the evidence that is consistent with such supposition.
    In short, I find no abuse of discretion or other reversible error.
    My colleagues disagree. I respectfully dissent.
