The hematocrit is the ratio of red blood cells, and at its highest point it did not go past 45. Most of the time it was below this. I'm not saying he blood doped or he didn't blood dope - I'm pointing out that many riders had higher crits than this but he still beat them, at the age of 37 after years out.
Armstrong's performance this year explodes the myth that doping was the key to his success. He is without doubt one of the all time greatest riders.
No, you are wrong.
His reticulocytes dropped to half their normal value during the Tour. Hematocrit and hemoglobin did not drop. Something was levitating those two values, and the most obvious answer is blood manipulation with EPO or transfusions. It seems clear that he was up to his old tricks.
Without dope Armstrong would have never placed in the top ten of the TdF.
I'm sure it is perfectly normal for a rider's blood parameters to completely change during the Tour.
