Wallace and Gromit said:I agree with your post in general, but in respect of the quoted section, the key point is that a guy in the US Open final only has to recover relative to the person they're playing. (Much that same as if two people are running away from a lion, you only need to out-run the other guy rather than the lion to survive.)
Thus, you can still have a 10% recovery advantage if you've recovered 50% compared to the other guy's 40%. Alternatively, if your still kn*ckered and can run at 8mps instead of your normal 10mps, you'll still do well against someone who's down to 7mps from their usual 10mps.
This accords with intuition and personal experience. You can do a hard effort one day and still do a very decent effort the next day, even though it wouldn't be your best. Obviously, doping would aid recovery, but the point is that it's perfectly possible to perform to a decent level the day after a hard effort without assistance. It's not like doping is required to enable a player to make it out of bed on the day of the final!
I read some analysis once about the relative success rate in the final given the timing of the semi final (ie before or after the ladies' final.) Can't remember the results, unfortunately. There was a theory that the guy from the earliest semi won more often than not due to different recovery periods.
last years we've seen 7 or 8 guys dominating in grandslam semis and finals.
none of those 7 or 8 guys was any less fit than the other, so your argument of relativity doesn't apply to the semis and finals of the slams.
it looks more as if you're (again) apologizing for what are rather clearly inhumane performances (dojokovic-nadal-murray-ferrer) from a fitness/stamina point of view. The assumption of heavy PED abuse in mens tennis (the top 100 in general and the top 10 in particular) "accords with intuition and personal experience" of what is humanly possible.
