This doesn't "clear up some facts" at all. Even if all of it were true - and your framing does strike me as highly suspect - none of you Vilas supporters have yet to explain away the fact that the men's tour in 1975 operated on the assumption that the contemporary rankings were correct and up to date. How is it fair to award these retroactive rankings to Vilas alone when his peers, some of whom aren't even alive, don't have this army of adherents to defend their own interests?
I'll "clear up" this confusion with an actually valid cross-sport analogy. Some of you might recall
the big brouhaha that erupted at the 2004 Summer Olympics after it was discovered that Yang Tae-young, the South Korean bronze medalist in the men's individual all-round gymnastics competition, had received for one of his routines a start value of only 9.9 rather than the correct 10.0, which might well have cost him the gold medal. So the SK delegation protested, followed by a counterprotest from their American counterpart to defend the gold medalist Paul Hamm (who FWIW I do think should've gracefully relinquished his title, at least before that self-serving letter from FIG President Bruno Grandi who called him to do just that).
But both the International Gymnastics Federation (FIG) and the IOC (and later the Court of Arbitration for Sport) held firm, concluding that, under FIG rules, the motion to correct the scoring error should have been filed during the competition and there had been no evidence of foul play. And guess what, Hamm supporters (per Wiki) also pointed out that "Yang's routine included 4 'hangs' instead of the 3 allowed, an error that, if caught, would have resulted in a penalty of .2 points, removing Yang from medal contention."
It's hard to disagree with that reasoning, however "unfair" it may be, or for that matter the US Olympic Committee's that an athlete should not be penalized after the fact for officials' blunder, but that's exactly what you Vilas supporters are calling for. You guys keep pushing this disingenuous narrative that there's no harm in "correcting" this one mistake for Vilas when rankings by definition concern more than one player and there's no such thing as co-#1 in (computerized) tennis. Well you're wrong, and I hope the above example finally explains why.
