That is a legitimate point, but I don't think it weakens the argument all that much. First of all when I say all top riders are doping, I mean all the actual top riders. I'm sure there are people who could have been top riders if they doped, or if no one doped, but aren't top riders because they don't and others do. Honestly I believe there are differences both in the programs used and in the responses, but of cause the guy who would have been number 2 in a clean race needs less gain to win than the guy who would have been number 100. The central question is if we imagine a hypothetical 100% clean race, how many would be within a needle-*** distance of the win? Obviously no definitive answer can be given, but I think the evidence suggests that there are many, and it only takes a few before the clean riders have no chance.I Watch Cycling In July said:The logic you present is quite convincing, but I'm still not quite convinced. I have a few nagging questions as follows:
If we assume the talent level of Kohl, Riis et al was 'pack fodder'
and the doping gains made by them is typical
and all the top riders are on a full program
then Kohl and Riis wouldn't have been able to catch up to the top riders.
So, the Kohl and Riis type examples are evidence that either:
1) there are substantial differences in the quality of program the most talented riders are on or
2) there are substantial differences in the way individuals respond to doping
All the arguments for why 'they're all doing it' presented in this thread, are weakened by one of the above.
I dug up a reference to the studies I mentioned earlier. One of them showed gain in endurance performance of 9-17%. Now that's a big variance, but it's also some very big gains even in the lower end of the scale.
