    OPINION
    PHILLIPS, Senior Circuit Judge:
    The Secretary of Commerce (the Secretary) appeals a district court
    order that invalidated the Department of Commerce's commercial
    catch quota for summer flounder for 1994 and that imposed another
    quota in its place. Because the district court misapplied the statutory
    2
    requirement that the Department set the quota in accord with the "best
    scientific information available," and consequently erred in invalidat-
    ing the agency-set quota, we reverse.
    I
    This case involves a challenge by a coalition of commercial fishers
    (the Coalition) to the 1994 commercial catch quota for summer floun-
    der promulgated by the Department of Commerce (the Department).
    The Department sets the quota every year through a complex process
    mandated by the Magnuson Fishery Conservation and Management
    Act, 
    16 U.S.C. § 1801
     et seq., and by federal regulations, 50 C.F.R.
    Part 625. Within the Department of Commerce are eight regional fish-
    ery management councils, established by the Act, whose job it is to
    develop plans for the conservation and management of the fish in
    each council's respective section of the American coastal waters.
    Among these bodies is the Mid-Atlantic Fishery Management Council
    ("the Council"), which has among its responsibilities the management
    of the summer flounder fishery, including the annual setting of the
    commercial catch quota.
    Before it could set annual quotas, the Council was required to
    develop a Fishery Management Plan for Summer Flounder, which it
    did in 1992. Amendments to the plan were promulgated in 1993 and
    1994 as well. As part of this Plan, the Council had to set for each of
    several years a "target fishing mortality rate." The fishing mortality
    rate is a statistic called F that expresses the depletion of the stock of
    fish attributable to fishers, whether by capture or by discard of fatally
    wounded fish or otherwise, in a given year. For 1994, the Fishery
    Management Plan set a target F of 0.53 and thus required that the
    commercial catch quota for 1994 be set at a level that would ensure
    that the actual F would not exceed 0.53. See 
    50 C.F.R. § 625.20
    (b)/(c).
    The process of setting the quota began, for present purposes, with
    the holding of a Stock Assessment Workshop, a gathering of marine
    scientists whose mission it was to estimate the size, age structure, and
    any other relevant characteristics of current populations of various
    species of fish off the Atlantic coast. The numbers produced by the
    Workshop for summer flounder were then presented to the Summer
    3
    Flounder Monitoring Committee (the Monitoring Committee), a sub-
    unit of the Council, on September 1, 1993 with recommendations
    from Council staff. The Monitoring Committee is a group of scientists
    constituted by the Department who are required to recommend,
    among other things, a commercial catch quota. The quota for 1994
    was to be based on the scientific information from the Workshop and
    was to be designed to ensure that the "fishing mortality rate," F, did
    not exceed the 0.53 level previously announced as the 1994 target by
    the Fishery Management Plan. The Monitoring Committee recom-
    mended a quota of 16,005,560 pounds. That recommendation then
    went to the Demersal Species Committee of the Council and to the
    Atlantic States Marine Fisheries Commission, an interstate organiza-
    tion with which the Council cooperates. Those two bodies, meeting
    jointly on September 23, approved the Monitoring Committee's rec-
    ommendation and passed it on to the Council which, in turn, recom-
    mended it to the Regional Director for approval. After the requisite
    notice and comment, during which no objections pertinent to this
    appeal seem to have been filed, the quota became final in early 1994.
    At the heart of the case is the way the Monitoring Committee used
    the Workshop's data regarding the "recruitment" of summer flounder
    --that is, the number of new flounder expected to appear in the popu-
    lation in 1994. At the Committee's annual quota-setting meeting, staff
    member Wendy Gabriel had presented the Committee with the geo-
    metric mean of the previous five years' estimated recruitments and
    the values one standard deviation above and below that mean. Then,
    on recommendation of Council staff, and specifically following the
    lead of Gabriel's presentation of the recruitment statistics to the Com-
    mittee, the Committee chose to recommend that the quota be set on
    the basis of a conservative estimate of recruitment. In particular, the
    staff had recommended, and the Committee then chose to use, an esti-
    mate of recruitment equal to the figure one standard deviation below
    the geometric mean rather than a recruitment estimate equal to that
    geometric mean. As a direct consequence, the Committee recom-
    mended that the previous year's quota be increased for 1994 only to
    about 16 million pounds (a 28% increase) whereas incorporation of
    the geometric-mean estimate would have boosted the quota to about
    19 million pounds.
    The lower quota was ratified at every step of review and published
    in the Federal Register accompanied by four justifications that closely
    4
    reflected those articulated in the original staff recommendation. As
    articulated in the Federal Register, the four reasons for using the
    lower estimate were the following: First, the summer flounder popula-
    tion was composed mainly of fish aged 2 and under; so an overesti-
    mate in recruitment would have great power to cause an overestimate
    in overall stock size and thus "would result in quotas that would
    exceed the target fishery mortality rate (F level)." Second, "the proba-
    bility of achieving the target F level is higher at the lower harvest
    level" with staff estimating an 80% probability that the proposed
    quota would keep actual F under target F. Third, three risky
    assumptions--that the previous year's quota would prove to have
    been adhered to, that all landings get reported, and that discard rates
    would not increase--underlay the estimate of the stock size and sug-
    gested that the stock-size curve might be overly optimistic. Fourth,
    since the target F was scheduled to decrease dramatically for 1996,
    it was better to err on the safe side now so as to minimize the chances
    of having to reduce the 1996 quota even more than was already antici-
    pated. J.A. 350. In short, the Council believed that the uncertainty in
    the recruitment estimates was so great and the long-term flounder
    population so fragile a resource for the fishers, especially in light of
    a coming reduction in the target fishing mortality rate for 1996, that
    a low estimate of recruitment was the prudent estimate.
    In challenging the quota, the Coalition argued that use of the lower
    estimate rather than the geometric mean in calculating the quota con-
    stituted a failure to use the best scientific information available as
    required by 
    16 U.S.C. § 1851
    (a)(2). After holding a three-day hearing
    to have the administrative record explained, the district court agreed
    and held that the quota, therefore, represented an arbitrary and capri-
    cious decision on the part of the Department. The court concluded
    that only the geometric-mean estimate could constitute the best scien-
    tific information available in this case. On this basis, the court held
    that "the 1994 commercial catch quota is invalidated to the extent that
    it deviates downward from the figure reached using the best scientific
    information available, which was 19.05 million pounds for 1994,"
    Fishermen's Dock Cooperative v. Brown, 
    867 F. Supp. 385
    , 386
    (E.D. Va. 1994), and ordered that the quota be reset at that figure. The
    key parts of the district court's opinion read as follows:
    The Court finds that the use of figures one standard devia-
    tion below the mean was arbitrary and capricious. The use
    5
    of a figure one standard deviation below the mean was cho-
    sen not because it was the best scientific information avail-
    able, but solely because it increased the percentages of
    reaching not a balanced result but a result which protected
    the summer flounder stock to the detriment of the fishermen.
    ....
    . . . The Council chose to implement a quota one standard
    deviation below the geometric mean, resulting in a quota of
    16.005 million pounds rather than a quota of 19.05 million
    pounds, a sixteen percent difference. Defendant's designees
    explained that using the lower figure increased the probabil-
    ity of reaching 0.53, the target fishing mortality for 1994,
    from 59% at the geometric mean to 81% with the lower fig-
    ure.
    This Court finds that the Council's decision to implement
    a quota one standard deviation below the geometric mean
    failed to utilize the best scientific information available, and
    therefore was arbitrary and capricious.
    ....
    . . . The commercial catch quota . . . should be reset using
    the figure derived from the best scientific information
    available--19.05 million pounds, the geometric mean,
    replacing the quota set at one standard deviation below the
    mean, or 16.005 million pounds.
    . . . Accordingly, this Court . . . ORDERS that the 1994
    summer flounder commercial catch quota be invalidated to
    the extent that it is less than 19.05 million pounds.

    This appeal by the Secretary followed. A number of environmental
    organizations and recreational fishers' organizations have filed an
    amicus brief in support of the Secretary's position.

    II
    In view of the nature of the district court's proceedings in this case,
    it is important that we define at the outset the standard under which
    we review its decision. We start with the standard under which the
    district court reviewed the agency action. It is prescribed in the
    Administrative Procedure Act (APA) and incorporated by the Magnu-
    son Act at 
    16 U.S.C. § 1855
    (b)(1)(B):
    The reviewing court shall--
    ....
    (2) hold unlawful and set aside agency action, findings,
    and conclusions found to be--
    (A) arbitrary, capricious, an abuse of discre-
    tion, or otherwise not in accordance with law;
    (B) contrary to constitutional right, power,
    privilege, or immunity;
    (C) in excess of statutory jurisdiction, author-
    ity, or limitations, or short of statutory right;
    (D) without observance of procedure required
    by law; . . . .
    
    5 U.S.C. § 706
    (2)(A)-(D).
    Our review of district court decisions made in review of agency
    action is generally de novo. Thus, we generally review the agency's
    action from the same position as that of the district court and seek to
    determine, as did the district court, whether on the administrative
    record the agency action was arbitrary and capricious or otherwise
    illegal under the statutory standards quoted above. Virginia Agricul-
    tural Growers Ass'n v. Donovan, 
    774 F.2d 89
    , 93 (4th Cir. 1985)
    ("The trial court was obligated to look to the administrative record
    and its view of the record is not entitled to deference."); Natural
    7
    Resources Defense Council v. United States Environmental Protec-
    tion Agency, 
    16 F.3d 1395
    , 1400-01 (4th Cir. 1993) (court of appeals
    review looks to the agency's action "to determine whether the record
    reveals that a rational basis exists for its decision").
    The Coalition points out, however, that where a district court has
    legitimately expanded the administrative record by holding a supple-
    mentary hearing, its decision might then be entitled to some unspeci-
    fied degree of deference from our court in review. It relies on then-
    Judge Breyer's exploration of the intricacies of judicial review under
    the APA in Sierra Club v. Marsh, 
    769 F.2d 868
    , 871-72 (1st Cir.
    1985):
    We should be more willing, or be less willing, to differ with
    a district court about the `reasonableness' or`arbitrariness'
    of an agency decision, depending upon the particular fea-
    tures of the particular case that seem to make a more inde-
    pendent, or a less independent, appellate court scrutiny of
    the administrative record appropriate. Where, for example,
    the district court's judgment turns on matters of fact that it
    has determined, or upon evidence presented by witnesses in
    court, or even upon lengthy district court proceedings in
    which knowledgeable counsel explain the agency's
    decision-making process in detail, we will show appropriate
    hesitation to overturn that judgment. [Citations omitted.]
    But, where the district court simply reviews a set of agency
    documents and, applying the same legal standard as we
    apply here, reaches a particular legal conclusion about the
    `reasonableness' of an agency's action, we have greater
    legal freedom to differ with the district court's ultimate
    characterization of agency behavior.
    Countering the suggestion that any deference is owed here, the Secre-
    tary challenges the propriety of the district court's expansion of the
    record, contending that its three-day hearing and ensuing expansion
    of the record was not warranted.
    Whatever the propriety of conducting such a hearing, we do not
    think it need have any effect on our review process. We have care-
    fully reviewed the record of that hearing and are satisfied that none
    8
    of the testimony received actually had the effect of substantively
    expanding the factual record before the agency. The testimony
    received essentially served only to educate the district court in the
    complexities of geometric means, standard deviations and
    probabilities--an education equally available to us. Because we are
    therefore satisfied that the district court reached its decision wholly
    on the basis of the administrative record itself and its own ad hoc self-
    education in statistics, we owe its decision no special deference deriv-
    ing from the extended hearing it conducted. Consequently, we will
    proceed to conduct our own independent review of the administrative
    record as being effectively the unexpanded record reviewed by the
    district court.
    III
    The district court held that, at least in the circumstances of this
    case, the statutory requirement that the agency use the "best scientific
    information available" translated to a rule of law that the agency use
    the geometric mean as its estimate of recruitment in setting the com-
    mercial catch quota for 1994. The Secretary argues on appeal that the
    agency's action in this case was in no way arbitrary, capricious, or
    otherwise illegal and that, even if it was, the district court overreached
    its authority in imposing a new quota rather than remanding to the
    agency.
    We agree with the essentials of the Secretary's primary argument.
    In explaining why, it is important at the outset to point out the limited
    scope of the Coalition's challenge to the agency action. It does not
    challenge the Fishery Management Plan or its target fishing mortality
    rate for 1994. It does not challenge the procedures used in producing
    the quota or the scientific validity of the data underlying the quota.
    It challenges only the Department's choice to rely on one estimate of
    recruitment rather than another, and contends that the district court
    was correct to hold that there was only one estimate consistent with
    use of the best scientific information available as required by 
    16 U.S.C. § 1851
    (a)(2). We disagree on that basic point. The district
    court's holding that the available scientific information on recruitment
    dictated one and only one possible quota reveals a critical misunder-
    standing of the nature of the information available.
    9
    The Act mandates that the agency conform to several"national
    standards," including the following:
    Any fishery management plan prepared, and any regula-
    tion promulgated to implement any such plan, pursuant to
    this subchapter shall be consistent with the following
    national standards for fishery conservation and manage-
    ment:
    (1) Conservation and management measures shall pre-
    vent overfishing while achieving, on a continuing basis, the
    optimum yield from each fishery for the United States fish-
    ing industry.
    (2) Conservation and management measures shall be
    based upon the best scientific information available.
    ....
    (6) Conservation and management measures shall take
    into account and allow for variations among, and contingen-
    cies in, fisheries, fishery resources, and catches.
    
    16 U.S.C. § 1851
    (a).
    No one contends that the Council's Fishery Management Plan is
    inconsistent with the above statutory standards. That Plan is imple-
    mented by 50 C.F.R. Part 625, which provides, in pertinent part, as
    follows:
    § 625.20 Catch Quotas and Other Restrictions
    (a) Annual Review. The Summer Flounder Monitoring
    Committee will review [certain data including"recent esti-
    mates of recruitment"] . . . to determine the allowable levels
    of fishing and other restrictions necessary to result in a fish-
    ing mortality rate of 0.53 in 1993 through 1995, and a fish-
    ing mortality rate of 0.23 in 1996 and thereafter . . . .
    10
    (b) Recommended Measures. Based on this review, the
    Summer Flounder Monitoring Committee will recommend
    . . . the following measures to assure that the fishing mortal-
    ity rate specified in paragraph (a) of this section is not
    exceeded:
    (1) The commercial quota will be set from a
    range of 0 to the maximum allowed to achieve the
    fishing mortality rate specified in paragraph (a) of
    this section; . . . .
    Next, in subsection (c), the regulations call for the Demersal Species
    Committee, the Council, and the Regional Director (both before and
    after public comment), each in turn, to consider what quota is "neces-
    sary to assure that the applicable fishing mortality rate specified in
    paragraph (a) of this section is not exceeded ." (Emphasis added.) This
    quoted language appears four separate times in that subsection.
    The sum of these provisions is that the Monitoring Committee is
    required to seek a fairly high level of confidence that the quota it rec-
    ommends will not result in an F greater than 0.53, even as it must be
    equally concerned to provide the fishing industry with an "optimum
    yield" both in the current year and over the long term. Although the
    regulatory language repeatedly calls for the Council to "assure" that
    the target F is "not exceeded," it cannot be taken to require 100%
    assurance. If taken literally, that language could mean that the Moni-
    toring Committee would have to recommend something close to clos-
    ing of the fishery to "assure" an acceptable F. But, of course, the
    statute does not contemplate regulatory overkill. It anticipates an "op-
    timum yield" for the fishing industry that is consistent with reason-
    able assurance that the actual F will be less than or equal to the target
    F.
    Also, while the language assumes that such a quota can be estab-
    lished on the basis of the "best scientific information available"--and
    so requires that the quota be set on that basis--it appears to say noth-
    ing about how that term is to be defined. It only mandates the consti-
    tution of committees of scientists to provide and evaluate such
    information.
    11
    In this case, the Monitoring Committee had before it, among other
    things, three estimates or predictions of recruitment for 1994 that
    were derived from research that, at least for purposes of this appeal,
    everyone agrees constituted the best scientific information available.
    One of the estimates was the geometric mean of the estimated recruit-
    ments for the years 1988 through 1992; that is, the midpoint of the
    probability curve of all possible recruitment estimates for 1994 as
    derived from the estimated actual recruitments of the previous five
    years. The other two estimates for 1994 were produced by traveling
    one standard deviation above and below the geometric mean along the
    curve of 1994 recruitment estimates. As is always true of the single-
    standard-deviation points along a normal curve, these high and low
    estimates represented the upper and lower limits of a range of esti-
    mates within which there was a 68% probability that the true recruit-
    ment would eventually lie. The geometric mean was just the middle
    value in that range, and the single-standard-deviation values were
    simply standard statistical markers for indicating the degree of uncer-
    tainty in the data.
    Thus, to illustrate, if the geometric mean were about 30 million fish
    with a standard deviation of about 10 million, all the Monitoring
    Committee would know from the three estimates presented to it was
    that the best science available predicted a 68% chance that the actual
    recruitment for 1994 would be somewhere between 20 million and 40
    million fish. No single point estimate on the curve had any assigned
    probability of being the ultimately correct one. But any range of esti-
    mates on the curve had a particular and easily derived probability of
    containing the ultimately correct number.
    One of the properties of the curve, then, was that it could provide
    the scientists and the administrators with the available research's best
    conclusions as to the ranges within which the actual 1994 recruitment
    was likely to lie. But another even more important property was that
    that curve apparently implied another curve; and this second curve
    provided, for any chosen point estimate of recruitment, the probability
    that the quota derived from that point estimate would ultimately pro-
    duce an actual F for 1994 of 0.53 or less. Crucially for this case, that
    latter curve in fact indicated that the 19-million-pound quota, derived
    from the estimate at the geometric mean, carried a 59% chance of
    eventually producing a 1994 F of 0.53 or less, whereas the 16-
    12
    million-pound quota, derived from the estimate one standard devia-
    tion below the mean, carried an 81% chance of eventually producing
    a 1994 F of 0.53 or less. And no one disputes the validity of these
    probabilities; no one suggests that they rested on anything but the best
    scientific information available.
    On the basis of this best available scientific information, then, the
    Monitoring Committee had to estimate what the true recruitment
    would be. If it estimated too high and set the quota accordingly high,
    then the smaller actual recruitment would be decimated by fishers
    operating under the high quota, with the result that F would exceed
    0.53. Alternatively, the Monitoring Committee could estimate that
    actual recruitment would be low and thereby increase its chances of
    not exceeding target F. Since the Fishery Management Plan called for
    assurance that target F would not be exceeded but not such absolute
    assurance as would result in grievously undershooting target F and
    denying the fishing industry its "optimum yield," the Agency's deci-
    sionmakers necessarily had some discretion to decide what precise
    degree of assurance it would seek within the uncertainty of the data.
    In exercising that discretion, these decision-makers consistently
    offered the four reasons recited above for recommending use of the
    lower of the two recruitment estimates and thus the lower of the two
    quotas that they had considered in light of the data presented: first, the
    truncated age structure of the summer flounder population, which
    magnified the risk to target F involved in any overestimate of the size
    of the recruitment class; second, the general proposition that a lower
    recruitment estimate provided a higher probability of assuring that
    actual F would turn out to be less than or equal to target F; third, the
    recognition that certain assumptions underlying the estimate of the
    flounder stock size might be overly optimistic; and, fourth, the belief
    that, since target F was to decrease significantly in 1996, it was better
    to deal with the current uncertainty in recruitment estimates by erring
    on the conservative side rather than risking an exacerbation of the
    painful quota decrease that had to come soon in any case.1 J.A. 350.
    _________________________________________________________________
    1 The Coalition argues in passing that this last justification is an unau-
    thorized acceleration of the Fishery Management Plan's call for a reduc-
    tion in target F in 1996 (not in 1994). That argument is correct as far as
    13
    These reasons do not justify the precise choice of an 81% probabil-
    ity of success or the choice to plug into the formula the specific
    recruitment estimate located at the one-standard-deviation-below-the-
    geometric-mean mark. See Brief of Appellee-Coalition at 36-39. Nor
    do they consistently explain why the choice of a conservative
    recruitment estimate was the best way to modify the quota rather than
    using a higher recruitment estimate but then simply lowering the
    quota itself to take account of all the uncertainties in the data. But
    they do reflect the Monitoring Committee's understanding that the
    recruitment estimate was the main source of uncertainty along the
    way to making a stock-size estimate and then setting a quota; and they
    do justify setting a quota that, taking that uncertainty into account,
    offered a high probability--if not 100% assurance--of achieving the
    regulatory goal of not exceeding target F. Moreover, at the Monitor-
    ing Committee's meeting and later in the process, the point was made
    that, "happenstantial" as the lower figure might be, it had the benefit
    of both providing a high probability of staying under target F and still
    allowing a substantial (28%) increase in the quota from the year
    before. It thus showed commercial fishers that the Department's mea-
    sures were not simply relentless attacks on the industry but beneficial
    over the long term for all concerned as the Act contemplated. J.A.
    189, 193, 325-27. The option of setting the quota so as to provide a
    90% or 95% probability of success was also considered but rejected
    as too heavy a short-term burden on the fishing industry. J.A. 325,
    193.
    In this situation, to assert, as the district court did, that the "best sci-
    entific information" required use of the geometric-mean estimate to
    dictate a quota that had only a 59% chance of not causing F to be
    exceeded, rather than use of an estimate that would provide an 81%
    chance of not causing F to be exceeded, is to misconstrue what the
    _________________________________________________________________
    it goes. But the Department's mandate in setting quotas is to manage
    great uncertainties in the data as best it can while taking the long view
    of the state of the fishery and its users, whether fishers or conservation-
    ists or anyone else. In that context, it seems fair to allow the Department
    to bolster its decision to err on the safe side with its observation that, if
    in fact its estimate proved to be low, it would at least have the benefit
    of easing the transition to the new target F in 1996.
    14
    best scientific information really shows in the context of the statute
    and regulations. A quota "based on" that information and designed to
    "assure" that the target F was not exceeded while still providing the
    fishing industry with an "optimum yield" could not properly be deter-
    mined by a court in judicial review to be, as a matter of law, only one
    that happened to provide a 59% chance of not exceeding F. The dis-
    trict court was correct that the specific choice of an 81% probability
    largely because it happened to correspond to one of the three recruit-
    ment estimates presented to the committee--when those three esti-
    mates were presented merely as indicators of the degree of
    uncertainty in the data--was, in a sense, arbitrary. But, within the
    terms of the statute and regulations, so would have been the choice
    of a 59% probability. See Brief of Amici Curiae at 27-28.
    When the regulations say that the Committee's recommendation
    should "assure" that target F is not exceeded, they do not say what
    probability of success (as derived from the best scientific information
    available) constitutes "assurance" of success. As long as everyone
    agrees, as everyone does, that the regulations do not require 100%
    assurance, the choice of how much assurance to indulge in must be
    a policy choice left to the reasonable exercise of the discretion of the
    statutorily authorized decision-makers. And that choice inevitably
    contains a degree of arbitrariness.
    In the event, those decisionmakers seem to have allowed them-
    selves to gravitate to a specific number--within the general range
    suggested by their reasoning--largely because that number happened
    to have been on the table as a standard deviation. If allowing them-
    selves to gravitate in that way constituted arbitrariness in the selection
    of the final number within the acceptable range of assurance, then the
    Monitoring Committee indulged only in the kind of arbitrariness that
    is inherent in the exercise of discretion amid uncertainty and not in
    the kind of arbitrariness that the statute condemns when it exists in
    tandem with capriciousness.
    To dispute this conclusion, the Coalition cites a handful of cases
    for the proposition that the APA requires a tighter connection than the
    agency has articulated here between the specific regulation adopted
    and the regulation's justifications. But evaluation of agency reasoning
    is inevitably an ad hoc enterprise, and the Coalition's cited cases sim-
    15
    ply do not present factual situations similar enough to our case to sug-
    gest that the agency failed to justify itself adequately. In fact, these
    cases do little but reaffirm the requirement that the agency have
    engaged in reasoned decision-making within the specific regulatory
    context.
    Thus, in Gas Appliance Mfrs. Ass'n v. Department of Energy, 
    998 F.2d 1041
    , 1047 (D.C. Cir. 1993), the court found a Department of
    Energy cost-benefit analysis inadequate because the Department had
    offered no information at all on how private companies might be able
    to conform to the assumptions of the analysis, much less what the
    costs of conforming might be or how those costs might compare to
    the benefits to be had. In Parravano v. Babbitt , 
    837 F.Supp. 1034
    ,
    1046 (N.D. Cal. 1993), similarly, the court found no record basis at
    all for the Secretary of Commerce's increase in a"salmon escapement
    floor." In Chemical Mfrs. Ass'n v. Environmental Protection Agency,
    
    28 F.3d 1259
    , 1265 (D.C. Cir. 1994), the court rejected the EPA's use
    of a model when the agency failed to respond meaningfully to a chal-
    lenger's "specific detailed evidence of a poor fit between the agency's
    model and that party's reality"; but, of course, the Coalition in this
    appeal does not even challenge the Council's model. Finally, in Motor
    Vehicle Mfrs. Ass'n of the United States v. State Farm Mut. Auto. Ins.
    Co., 
    463 U.S. 29
    , 43 (1983), the Supreme Court said that usually "an
    agency rule would be arbitrary and capricious if the agency has relied
    on factors which Congress has not intended it to consider, entirely
    failed to consider an important aspect of the problem, offered an
    explanation for its decision that runs counter to the evidence before
    the agency, or is so implausible that it could not be ascribed to a dif-
    ference in view or the product of agency expertise." The Court then
    went on to invalidate the agency's action on the basis of its utter fail-
    ure to consider obvious alternative actions. State Farm, 
    463 U.S. at 46-51, 54-57
    . And it reminded those who would challenge agency
    action that often "the available data do not settle a regulatory issue,
    and the agency must then exercise its judgment in moving from the
    facts and probabilities on the record to a policy conclusion." State
    Farm, 
    463 U.S. at 52
    . Far from supporting the Coalition's position,
    State Farm offers a description of legitimate exercise of agency dis-
    cretion that neatly suggests the Council's actions in this case. In sum,
    these cases actually require an agency to do what the Council did here
    --that is, reason its way to a decision without pretending that that
    16
    decision reflected some degree of rational perfection beyond what the
    inherent uncertainties of the available data permitted. See Leather
    Industries of America v. Environmental Protection Agency, 
    40 F.3d 392
    , 409 (D.C. Cir. 1994) ("Where the agency's line-drawing does
    not appear irrational and the [challenger] has not shown that the con-
    sequences of the line-drawing are in any respect dire . . . we will leave
    that line-drawing to the agency's discretion."); see also 1 Kenneth C.
    Davis and Richard J. Pierce, Jr., Administrative Law Treatise, § 7.5,
    at 326-332 3d ed. (1994) (citing cases and arguing the futility of
    courts' expecting agencies to reduce every exercise of discretion to
    precise argument).
    IV
    Our independent review of the record satisfies us that the agency's
    process of setting the 1994 quota was conducted in good faith, pur-
    sued with a proper understanding of the law, based on the best scien-
    tific information available, and adequately justified by the agency. If
    there was an inevitable element of arbitrariness in the decision, there
    was not the least caprice. The district court could not properly hold
    that the quota was not based on the best scientific information avail-
    able where, as we hold, the record demonstrates that the agency fully
    understood the meaning of the data before it and chose to adopt a
    quota that, on the basis of that information, offered a high probability
    of meeting its regulatory mandate while also allowing the fishing
    industry to increase its harvest for 1994 over that of 1993. Accord-
    ingly, we will reverse the district court's judgment, uphold the
    17
    Department's 1994 commercial catch quota, and dismiss the Coali-
    tion's action.2
    REVERSED
    _________________________________________________________________
    2 We recognize, but need not further address, the practical problem of
    adjusting the ongoing annual quota-setting process to accommodate our
    decision upholding the Department's 1994 quota. The cyclical adminis-
    trative process of course has had to continue while this litigation pro-
    ceeded. The problem of adjusting it to successive decisions made in
    judicial review originated with the district court's decision which, in late
    1994, effectively increased the agency's 1994 quota by 3 million pounds.
    About six weeks later, responding to a show cause order as to why the
    court's order had not been implemented, the Department agreed to a con-
    sent order to control the matters at issue pending this appeal. Under that
    order, the Department was required to apply to 1995 the 3-million pound
    quota increase originally ordered for 1994. In its brief to this court, the
    Department indicated that were it to prevail, it would accommodate our
    decision in its favor by rescinding the 3-million pound increase of the
    1995 quota. With 1995 now past, that particular accommodation of
    course is no longer possible. We need not attempt to direct just how our
    invalidation of the judicially-ordered increase should now be worked into
    the process. It suffices to reject, as we do, the Coalition's argument that
    because the consent order was not appealed by the Secretary, the 3-
    million pound increase it ordered cannot be rescinded. That argument is
    without merit; the consent order specifically recited that it was entered
    without prejudice to the Department's "pursuing an appeal from the
    court's prior orders." Fishermen's Dock Cooperative, et al. v. Brown,
    No. 2:94cv338 (E.D.Va. Dec. 19, 1994) (consent order). With that
    decided, we may leave to the Department's properly exercised discretion
    the matter of how the invalidated increase is to be accommodated in the
    ongoing quota-setting process.
