I believe this data is superior to outside subjective judgments regarding rider performances. In fact, all this data suggests that the talk of extraterrestrial performances at the 2012 Tour is biased - not surprising to anyone like myself who does research on judgment and decision-making. The anti-Sky theorists suffer tremendously from a bias blind spot - far too overconfident in their own judgments and resilience to biased judgments.
If anyone's judgment deserves to be weighted more positively, it is that of managers like Vaughters. If 2012 Sky Tour performance was fishy, he would either call them out or remain silent. He would not be praising them as evidence of clean cycling. Remember, he still feels jilted and betrayed by Wiggins.
The fact is, there is no physiologically suspicious 2012 Tour data, but, rather, data showing both historically-normed realistic performances and a reduction in outputs. While this is not enough to infer clean cycling, it is likewise not evidence of doping - this thread involves literally thousands of posts claiming the contrary, namely that these performances are obviously doped. Either willful distortions or biased post hoc rationalizations stemming from some emotional dislike of Sky, probably some misplaced schadenfreude...
