Mike & Barto–
If PEDs have been prevalent since the 60s (at least since the 70s), then how can we even compare the performance levels to those who are clean? The 100m would have nearly been a WR 10 years ago… and INTO A HEADWIND. The 200m times are crazy (maybe not from the championship final, but look at the overall event), the 400m winning time was great and the top 3 were all on or near WR pace at 300m, etc. etc.
What times were faster (absolutely and when you control for conditions):
Times from Athens 04 or Osaka 07 or were they pretty close?
And since when does it have to come out of left field to be PED use? If you have been using them for years, then why would that happen? Why would it only happen in the championship final as opposed to the entire season?
