I disagree. It pretty much is just what you believe, as you are never able to proved any factual basis on demand, just mere speculation. On the one hand, you repeatedly concede no doping/performance data exists, nor can exist, for the fastest elite performances from the fastest athletes, and on the other hand, without any figures, you say doping benefit in the last five decades is significantly greater than all other factors combined. It is basic first grade math that the less than operator requires two numbers, and you have provided none.
Despite appealing to "all the evidence", you do not provide any evidence here -- just another appeal to false authorities, as your "above all" starting point.
Decades of doping in E. Germany, Russia, and for a short while, China, could be used to argue steroids for women -- an argument I would concede, and have conceded many times -- but otherwise, decades of state sponsored doping (steroids and blood doping) produced no significant results for E. German or Russian men in distance events, and only produced results for women in sprints to middle distance events, and one marathon runner.
