Armstrong, Ullrich, Pantani, Valverde, Contador etc have all had plenty written about how dominant they were at a young age, undoped Race-Horse to doped Race-horse is how it works in horseracing too, they don't say "we'll buy a horse 50% less thoroughbred, dope it and then beat the doped 100% thoroughbreds", so Donkey to Race-Horse is a red herring anyway if everyone is maximising their levels to more or less an extent, that extent simply isn't considered when banned with a doping violation anyway, you're a cheater, it's as simple as that, We don't know the extent of a caught doper's doping whatsoever only what they were caught for which might be 1 of 1 of 1 of 10 other doping violations that were not found.
