Well, I think it’s about logic. I must cling to that approach anyways, because of my lack of that sort of experience you told convinced you about the widespread doping in track and field. But of course feel free to correct me if my logic clearly is in mismatch with reality….
1.Prevalence: With you I think this is the key point. -What is the percentage of doping among elite athletes f.ex sub 3.35 (1500m) and sub 3.30, and how do we know…. Well, the last question first: I see four ways of information gathering. -One can test the athletes -One can investigate (as in Lance Armstrong and M. Jones) -One can study the blood passes -One can make an anonymous survey…
Testing: One can increase overall testing, but there will always be suspicions about a significant number never caught..The same with investigation. Maybe there is more to be seen in the blood passes -suspicious traits not enough to conviction, but to make an presumption (but this is a dangerous path legally and scientifically). Last: Anonymous survey -one has to ask directly: Have you / or do you do doping? But we know the answers can’t be trusted… Conclusion: There’s no way of knowing how prevalent doping is among the elite! You don’t have a clue, and I don’t have a clue! Therefore you loose all your base for your doping claims -you cannot draw a line on 3.30 or say anything of prevalence or the limit for human clean performance at all! And I, well I don’t loose a thing, because I have never pretended to have other things than assumptions, logic and some subjective reasoning / careful analysis of pros and cons / probability… Without saying “I know”!
I guess you have done some kind of interpolation from experience among sub elite, (where doping may be prevalent and not all that hidden) and over to elite athletes, but you cannot do a thing like that, because there is no necessary correspondence..! Or you are basing a lot on rumours or sayings or feelings around your thoughts of progression, limits of human capacity and the effect of drugs. But fact is that you know nothing, nor do I, or anybody else.
2. Point 1 is the factual part: What we know. (That we know that we don’t know anything about prevalence). Here in point 2 is how we can guess something about probability for doping / not doping based on subjective reasoning and falsification -but we need to know that this is highly speculative and not facts. We must be somewhat humble… -I have a lot here, but have to save it for a later post (too many words already…)
