<yeah, maybe many WRs greater than Beamon's (percentagewise) - but none in 'established' events. Like Cy Young's 511 wins, one record (6.58% improvement) that won't ever be broken. (at least let's hope not ..enough WRs under suspicion...)>
Shouldn't really delve too much into baseball here. But if we do, what about Satchel Paige?
I think he is said to have had about 50 no-hitters, as against about 8 for the "best on record". I do not know how many wins Paige had, but gather it is said to be well over 1000.
