Fair enough, however I'd like you to consider that Schippers gradual progress as listed at the IAAF sire. She ran incredible times (for an hepthatlete as since the beginning). Running 22.03 in wet, cold conditions without competition into a headwind last year in Zurich beats Felix 22.02 hands down. Translated to Beijing conditions she was well capable of doing 21.8 last year. She always had the talent to become a very good sprinter, however take a route through the heptathlon. She is convinces that that experience led to those times we are seeing.
I agree with Tompson though... her improvements are off the record. But then again, innocent until proven guilty... and that includes Flojo. You won't get me buying into the "clean" world record. There is only one and that is from flojo, suspicious or not.
Again whether she is clean, we both do not know. But she is innocent until proven otherwise. Otherwise we should be handing over the 200m gold medal to either mc grown or asher smith or even if you want to stretch it to a runner that did not even make it into the final.
