On Pocagar aerobic engine and recovery capabilities

I still don’t understand how all of this would prove doping. Even if someone did show some great improvement they could just all chalk it up to finally finding the perfect training for them, while improving their diet and sleep, having an amazing team environment, altitude, etc. Unless they are putting out like 8+W/kg it’s basically all circumstantial evidence that proves nothing and would just fuel every armchair GC contender to accuse people of something suspicious.
