No it hasn't. Ashenden's skirmish with the UCI has blown the bio-passport scheme wide open. Positive, negative, suspicious, just doesn't seem to matter.
We now know there are suspicious samples that are analyzed as clearly positive and not passed onto experts. Rickshaw understands it well. No doping controversy.
I would agree with you if you said an athlete had to be a little bit smarter doping than prior the bio-passport. But, other than that, doping is wide open as long as the UCI favors the cyclist.
To make matters a little worse, the UCI has taken over the process of routing samples to experts. Before it was Saugy's lab's job and we know that guy met with riders to explain it all to them at the UCI's request and we know they didn't route clearly positive samples.
