OPINION
K.K. HALL, Circuit Judge:
Lisa Lee Mines petitioned for review of an order of the Department of Labor’s Benefits Review Board (BRB) affirming the award of black lung benefits to Alva Rutter, a former coal miner. A panel of this court reversed and remanded. Lisa Lee Mines v. Director, Office of Workers’ Compensation Programs, 57 F.3d 402 (4th Cir.1995). Rutter, who had proceeded pro se before the panel, obtained counsel and sought rehearing en banc. Having granted such rehearing, we now affirm.
I.
Putting aside for a moment the question on which the parties disagree, we must first note that Alva Rutter’s medical condition unquestionably qualifies him for black lung benefits. He is the very paradigm of the man Congress intended to compensate. According to x-rays taken in 1988 and 1989, he has profuse small opacities in all six lung zones, upon which has developed complicated pneumoconiosis, or, by its more dauntingly descriptive name, “progressive massive fibro sis.” One of the 1989 readers classified the large opacities in Rutter’s lungs in Category B, which means that they are greater than two inches in diameter. Because progressive massive fibrosis is just that — progressive— Rutter is doubtless worse off now, seven years later, and he is not yet an old man. He spent his entire working life — 32 years— in the mines, most of it loading coal by hand. Because of this long tenure, he need prove nothing more than his complicated pneumoconiosis to be entitled to benefits. 30 U.S.C. § 921(c)(1), (3); 20 C.F.R. §§ 718.302, .304. In short, the substance of Rutter’s claim is fine.
II.
Procedure is the rub. In 1986, without the assistance of an attorney, Rutter applied for black lung benefits. He was still working at the time. An x-ray he submitted showed complicated pneumoconiosis; nonetheless, a Department of Labor claims examiner sent him a form denial. Rutter did not pursue the claim further.
In April 1989, he filed a new claim. Because of the denial of his earlier claim, this one was subject to the “duplicate claims” regulation at 20 C.F.R. § 725.309(d), which states, in relevant part:
If the earlier miner’s claim has been finally denied, the later claim shall also be denied, on the grounds of the prior denial, unless the deputy commissioner determines that there has been a material change in conditions—
This time a deputy commissioner in the Department awarded benefits. The responsible operator, petitioner Lisa Lee Mines, requested a hearing. Lisa Lee’s challenge to the deputy commissioner’s decision was limited to whether Rutter had made the threshold showing of a “material change in conditions.” The parties then agreed to submit the question on the existing record.
On October 11,1991, an administrative law judge (ALJ) issued a decision and order awarding benefits. After canvassing the evidence, the ALJ concluded, “the medical evidence in 1989 shows a definite progression of the disease occurring over another interval of time resulting in the Claimant’s reduced capacity to do his former coal mine work.”
The ALJ then went on to hold that, if the evidence were inadequate to establish a material change in conditions, Rutter would still be entitled to benefits. According to the ALJ, the 1986 denial was erroneous on its face and “null and void ab initio.” Consequently, “it is believed that a determination whether or not the new evidence establishes a change of condition is immaterial.” The ALJ set the date of onset of disability as August 1,1986.
On September 30, 1994, the BRB modified the award. It held that the ALJ’s finding of an actual progression of Rutter’s disease was sufficient to satisfy its Spese test for material change in condition. However, the BRB held that the ALJ had no power to reopen or review the denial of the 1986 claim, which became final upon Rutter’s failure to appeal or move to modify it. The BRB therefore affirmed the award but changed the date from which benefits were payable to April 1, 1989. Lisa Lee then filed a timely petition for review in this court.
III.
Lisa Lee’s argument is as easily stated as it is counterintuitive: Rutter must now lose because he clearly should have won in 1986. He likely should have; the ALJ here was so appalled by the 1986 denial that he deemed it “void ah initio.” Nonetheless, though we might share the ALJ’s sentiment, we agree that his reasoning was flawed. The 1986 denial is final, see Pittston Coal Group v. Sebben, 488 U.S. 105, 122-123, 109 S.Ct. 414, 424-25, 102 L.Ed.2d 408 (1988), and for present purposes, we must assume that it was correct.
The panel rejected the BRB and Director’s standards for determining whether there was a material change in Rutter’s condition. The panel criticized the BRB’s Spese standard because it “impermissibly allows a claimant to present ... evidence available at the time of the initial decision tending to show that the initial decision was in error.” 57 F.3d at 406. The Director’s standard met similar criticism: “it permits reconsideration of critical determinations underlying a decision denying benefits.” Id. at 407. Instead, the panel adopted the Seventh Circuit’s test, which, as applied, meant that the miner must show that his condition has changed on every element previously decided against him. See Sahara Coal Co. v. Director, OWCP, 946 F.2d 554 (7th Cir.1991). Moreover, as in Sahara Coal, the panel required inquiry into the evidence behind the earlier decision, rather than merely accepting the factual predicate of the earlier decision as correct. Consequently, the panel remanded for an all-but-certain finding that Rutter had actually been eligible for benefits in 1986, so his current conceded eligibility could not evince a material change in condition. We disagree with this reasoning.
If the 1986 denial is “final” in a legal sense, we must accept the correctness of its legal conclusion — Rutter was not eligible for benefits at that time — and that determination is as off-limits to criticism by the respondent as by the claimant. Only by repudiating the 1986 judgment and its necessary factual underpinning can no- change in Rutter’s eondition be found. We believe that such repudiation is improper.
Accepting the correctness of a final judgment is more than legalistic tunnel vision; it is a practical — perhaps the only practical— way to discern a concrete form in the mists of the past. The ease we might feel at second-guessing this final judgment ought not tempt us to overestimate our retrospective perspicacity; most black lung claims involve a mixed bag of test results and wildly divergent medical opinions. The final decision of the ALJ (or BRB or claims examiner) on the spot is the best evidence of the truth at the time.
In this regard, the panel opinion could be read to imply that the deputy commissioner made an express finding of fact in 1986 that Rutter had complicated pneumoconiosis. See 57 F.3d at 404 (“A Department of Labor deputy commissioner denied that claim, finding that although Rutter had presented evidence of complicated pneumoconiosis, he had not established that the disease was caused by coal mine work, or that he was totally disabled by the disease.”) (emphasis added). This implication is mistaken. The form denial neither states that Rutter has complicated pneumoconiosis nor acknowledges that he “had presented evidence” of it. It may have been obvious to all who could and would see, but a finding that should have been made is not a finding that was made.
Not only does the denial of benefits itself necessarily imply the opposite finding, see 20 C.F.R. §§ 718.302 and .304, but the language of the summary denial form can logically lead only to that finding. In one part of the correspondence, Rutter was told that he had not proved total disability; in another, he was invited to submit additional evidence on that issue, and was told that proof of complicated pneumoconiosis would suffice.
We accept the final 1986 decision, as well as its necessary factual predicate, as correct. Rutter has shown a stark change in condition, and he is entitled to have his 1989 claim decided on its own considerable merits.
IV.
A.
Rutter’s is just a single case, and our reasons for affirming the award could end here. However, the proper standard to determine whether a given claimant has proved a “material change in condition” has recently split the circuits, and we now take this opportunity to align ourselves with the Third and Sixth Circuits, rather than the Seventh.
In choosing the proper standard, we have three candidates: (1) the BRB’s Spese formulation, which broadly looks to whether the newly submitted evidence favorable to the claim has a “reasonable possibility” of changing the prior result; (2) the Sahara Coal test, adopted by the Seventh Circuit and the panel here, which requires the miner to show that he “did not have black lung disease at the time of the first application but has since contracted it and become totally disabled by it, or that his disease has progressed to the point of becoming totally disabling although it was not at the time of the first application,” 946 F.2d at 556; and (3) the Director’s “one-element” standard, which requires the claimant to prove, under all of the probative medical evidence of his condition after the prior denial, at least one of the elements previously adjudicated against him. The Director’s standard, to which we owe deference, is easily the most reasonable and workable of the lot. To explain why, we should begin with background principles.
B.
A new black lung claim is not barred, as a matter of ordinary res judicata, by an earlier denial, because the claims are not the same. The health of a human being is not susceptible to onee-in-a-lifetime adjudication.
It is almost too obvious for comment that res judicata does not apply if the issue is claimant’s physical condition or degree of disability at two entirely different times, particularly in the case of occupational diseases.
3 A. Larson, The Law of Workmen’s Compensation, § 79.72(f) (1989). The issue in 1986 was Rutter’s condition in 1986, and his future condition was not and could not have been litigated then.
Thus, nothing bars or should bar claimants from filing claims seriatim, and the regulations recognize that many will. See, e.g., 20 C.F.R. § 725.409(b) (if prior claim has been denied by reason of abandonment, “a new claim may be filed at any time and new evidence submitted where [the claims modification process is unavailable.]”) The duplicate claims regulation, 20 C.F.R. § 725.309(d), does not bar new claims, but rather directs that they shall be denied based on the earlier denial absent a threshold showing of a material change in conditions. Thus, the regulation simply interposes a rebuttable presumption that nothing has changed, apparently to lessen the administra tive burden of the black lung program. It creates a sort of presumptive finality operating upon a future dispute, a finality that must not be confused with ordinary res judicata, which cannot look forward.
The Sahara Coal test, as applied by the panel here, forces the claimant to show a material change on every element that was previously decided against him. This approach fails to account for the frailty of alternative holdings. A black lung claimant must prove every element of his claim. If he loses on one, or two, or three elements, the end result is the same: a denial. For this reason, if he loses on more than one element, but only one is in fact a correct basis for denial, the law does not impose a duty upon him to file a meaningless appeal to “correct” the erroneous alternative holdings. Otherwise, “the rule might be responsible for increasing the burdens of litigation on the parties and the courts rather than lightening them.” Restatement (Second) of Judgments § 27, comment i (1982). Accordingly, holdings in the alternative, “either of which independently would be sufficient to support the result, ... [are] not conclusive with respect to either issue standing alone.” Id.
Here we meet up with something of a dilemma. We must have an anchor in the past with which to compare current conditions, but alternative holdings are not necessarily conclusive.
The Director’s approach strikes a reasonable balance. Each of the alternative holdings is presumed to have been correct when made and to continue to be correct through time. Because of their tenuous nature, however, disproof of the continuing validity of just one of the alternative holdings is enough to establish a material change in condition. We defer to the Director’s reasonable interpretation of the duplicate claims regulation. In doing so, we join the Third and Sixth Circuits. Labelle Processing Co. v. Swarrow, 72 F.3d 308 (3rd Cir.1995); Sharondale Corp. v. Ross, 42 F.3d 993 (6th Cir.1994).
C.
In comparison to the Director’s approach, Spese and Sahara Coal come up short. The Spese test is too vague to be applied consistently, contains illogical evidentiary rules (it permits resort to evidence available before the prior denial and forbids consideration of contrary probative evidence), and arguably sets too low a threshold (“reasonable possibility”) to discern “material” changes in condition.
Sahara Coal has two flaws. First, it founders on issue-preclusion principles where there are alternative holdings in the first claim, as discussed above. Second, and more importantly, it is the only one of the standards that permits — in fact demands — a plenary review of the evidence behind the first claim. For example, it is not enough for the miner to rely on an AL J’s final determination that he did not have pneumoconiosis or was not disabled by it. The miner must affirmatively prove that these adverse determinations were correct. To use that court’s own words, its standard “makes mincemeat of res judicata.” 946 F.2d at 556.
V.
We are not unmindful of the possibility that the Director’s standard might encourage abuse of the administrative process by wily claimants and their wily lawyers. After today’s decision, an unsuccessful claimant will doubtless schedule a morning appointment with a compliant physician for a year and a day after the denial of his claim. Armed with evidence contrary to an element previously found against him, the claimant will file a new claim that afternoon, and so on, ad infinitum.
This scenario belongs to that genre of horribles that seems impressive in academic debate but has little relevance to real life. Any claimant who wants to be a perpetual litigator can already be a perpetual litigator, and in a much easier fashion. The day before his hypothetical doctor’s appointment, the miner may file a request for “modification” of the earlier denial. For the claimant, modification is a far more attractive option than a new claim, because, in addition to a change in conditions, it can be based on a “mistake in a determination of fact” in the original denial. 20 C.F.R. § 725.310(a). No new evidence is required. A claims examiner may “ ‘correct mistakes of fact, whether demonstrated by wholly new evidence, cumulative evidence, or merely further reflection on the evidence initially submitted.’ ” Jessee v. Director, OWCP, 5 F.3d 723, 724 (4th Cir. 1993) (quoting O’Keeffe v. Aerojet-General Shipyards, Inc., 404 U.S. 254, 256, 92 S.Ct. 405, 407, 30 L.Ed.2d 424 (1971) (per curiam) (decided under Longshore and Harbor Workers’ Compensation Act)). Because the § 725.310(a) procedure modifies the original denial, the claimant has the opportunity to collect benefits from an onset of disability date preceding the original denial. The miner who waits a year and a day must file a brand new claim, and, as we have stated above, the prior denial becomes a final adjudication that the miner was not disabled by pneumoconiosis as of the date of its issuance.
Moreover, a miner who wanted to file duplicate claims ad infinitum would have to live ad infinitum. The black lung claims process is extraordinarily slow; today, in 1996, we still routinely hear eases involving the 20 C.F.R. § 727.203 interim presumption, which was superseded by the permanent regulations sixteen years ago. See 20 C.F.R. § 718.2 (permanent regulations effective March 31, 1980). Few miners have the time or wherewithal to go through the system twice; all too many die during the first run.
The risk of sporadic abuse of the duplicate claims process is far outweighed by the necessity that there be some such process and by the utility of the Director’s approach to it. As we emphasized above, pneumoconiosis— especially in the advanced form from which this claimant suffers — is a progressive disease, and no rational system of law or of medicine could stand on the proposition that it can or must be measured only once. A rational system would simultaneously account for the progressiveness of the disease, discourage useless appeals of alternative holdings, and require, at the threshold, a palpable basis to believe that conditions have changed over time. The Director’s “one- element” approach accomplishes this difficult task.
VI.
Finally, we return to Mr. Alva Rutter. In clinical terms, the change in his condition has been very real, even if we reexamine the 1986 evidence. The ALJ found that, in 1986, Rutter had small opacities of 2/2 profusion in four of six lung zones, with large opacities of category A (greater than one but less than five centimeters in diameter). By 1989, small opacities clogged all six lung zones, in greater profusion (2/3 to 3/2), and large opacities had progressed to Category B (greater than five centimeters). In 1986, notwithstanding his advanced disease, Rutter could work and support his family. Now he cannot. From Rutter’s viewpoint, the change in his condition could scarcely be more “material.”
The award of benefits is affirmed.
AFFIRMED
. One reader classified the profusion as 2/3 and the other as 3/2. There are twelve levels of profusion classification for the radiographic in-teipretation of simple pneumoconiosis. 2/3 is the fourth highest profusion and 3/2 the third. See N. LeRoy Lapp, "A Lawyer’s Medical Guide to Black Lung Litigation,” 83 W. Va. Law Rev. 721, 729-731 (1981).
. Rutter was bom June 5, 1936. At the time of his 1989 claim application, he had five minor dependent children living at home.
. Rutter was still working as a miner helper at the time, though, the very next month, his breathing problems led to a transfer to less arduous toil. He retired in January 1990.
. "Deputy commissioners” are now referred to as “district directors.” 20 C.F.R. § 725.101(a)(ll) (1995).
. Spese v. Peabody Coal Co., 11 BLR 1-174, 1-176 (Ben.Rev.Bd.1988) (change in conditions is established by evidence that is “relevant and probative so that there is a reasonable possibility that [it] would change the prior administrative result.”).
. We can only speculate that Rutter would have had the 1986 denial reversed on appeal to an ALJ, the BRB, or this court. For all we can know, had Rutter requested a hearing, the respondent would have produced a dozen radiologists to deny that his x-rays were positive for complicated pneumoconiosis.
Moreover, it is at least conceivable that the claims examiner consciously rejected the x-ray-evidence of complicated pneumoconiosis as inconsistent with Rutter’s "essentially normal” pulmonary function tests.
. The denial of benefits was accomplished through Department of Labor form letter No. CM-1000a (Jan. 1982) and its “Guide for Submitting Additional Evidence,” No. CM-1000g (Jan. 1982). The letter states, as pertinent here:
Dear Claimant:
We have carefully reviewed the evidence in your claim under the Black Lung Benefits Act.
This evidence does not show that you qualify for black lung benefits.
******
You do not qualify for benefits because the evidence in your claim
******
2. (X) does not show that the disease was caused at least in part by coal mine work; [and]
3. (X) does not show you are totally disabled by the disease. Totally disabled means you are unable to perform the type of work required by your coal mine work because of a breathing impairment caused by pneumoconiosis (black lung disease). The results of your medical evidence are shown on the enclosed explanation.
The guide for submitting additional evidence directed Rutter to submit proof of total disability due to pneumoconiosis. Five types of such proof were listed; the very first was "X-ray or other evidence confirming the presence of complicated pneumoconiosis (the most severe form of black lung disease)!.]”
. Pauley v. BethEnergy Mines, Inc., 501 U.S. 680, 696, 111 S.Ct. 2524, 2533-34, 115 L.Ed.2d 604 (1991); see generally, Chevron U.S.A., Inc. v. Natural Resources Defense Council, 467 U.S. 837, 845, 104 S.Ct. 2778, 2783, 81 L.Ed.2d 694 (1984).
. Lisa Lee correctly notes that there is no express statutory basis for the duplicate claims regulation, and asserts that it is invalid. The premise of this argument is that, absent the regulation, miners could not hie new claims. But of course they could; as the excerpt from Larsons treatise quoted above makes clear, common-law res judicata has no applicability where the issue is a person’s health at two different times.
. If, as we have held above, the necessary factual premises of the 1986 decision must be accepted as true, Rutter would win under any standard. Because of statutory presumptions, see supra at 3, proof of complicated pneumoconiosis, in and of itself, establishes “all elements” of Rutters claim.
. We do not endorse, however, the closing paragraph of Sharondale Corp., 42 F.3d at 999, where, after adopting the Directors standard, the Sixth Circuit seems to have required consideration of the evidence behind the earlier denial to determine whether it "differ[s] qualitatively” from the new evidence. Even if we agreed with such a requirement, Rutter certainly satisfied it here, inasmuch as the ALJ found an actual deterioration in his condition.
. The Seventh Circuit did speculate that this rule might allow for an exception if the claimants current condition were “substantially worse,” lest the possibility of his prior entitlement “complicate the proceeding unduly. 946 F.2d at 558. Where the claimant is only slightly worse off,” however, he must prove that he correctly (and slightly) missed the disability threshold the first time around. Id. This requirement lends itself to evidentiary mischief, inasmuch as the prior file will generally contain "admissions” by the miner of all of the elements of entitlement.
. Of course, an especially cagey claimant could abuse the system by simply dropping each claim after its administrative denial, filing anew in a year and a day, and waiting, as if for the lottery jackpot, to strike it rich with a sympathetic claims examiner.
This elaborate ploy could happen; all sorts of odd things happen. But it simply does not describe typical human behavior. Our lottery winner, for all the skill of his gambit, would quickly find himself faced with a controversion of the claim from the responsible operator, and he would then get a much belated chance at his decade of litigation. Out-of-work coal miners, disabled or not, generally need money badly enough to forgo such pointless intrigue in favor of honestly and earnestly prosecuting their claims.
. Accepting this proposition would put the miner in an absurd dilemma. Should he file now, and risk losing everything by filing a bit too soon,” or should he wait a few years until his disease has progressed to a more favorable” stage?
