Look... I told you (& of course to everybody round here) many times "I don´t know" (if they are doping or not). I said they certainly (this may not the
exact words I used) are in a "grey area", bending the rules but not stepping over it. What is the grey area? If I had known, I would have told. But it seems they do something in the area of extreme wight reducing w/o losing power. If I look at Froomes leg picture, it shows only bones and skin. Mottet was on diet only. It worked for him pretty well. May Sky advanced existing methods to the extreme.... (As I said earlier, I am no expert in this watts stuff. But AFAI understand it, simple math does help me. 380 watts on 65 kg gives 5.8 W/Kg. Losing 3 kg on marginal gains

higher that number to 6.1 W/kg)
The same is true the other way round: Nobody (at least the pages I read) came up with a clear picture what kind of doping method Sky allegedly uses. All I hear is they are doping. So you might further explain what the difference of these two opinions is. I can´t explain the exact use* of method in the grey area, the doping theorists can´t come up with what the drug is. I guess you would agree that "existing drugs" are open to everybody, not solely for Sky. Right?
* Add in the painkiller use, it pretty much helps to prolong extreme performance...
