I haven't read through the rest of this thread, so someone else may have a similar comment, but I'm going to jump in here.
The cited study does NOT show that EPO affects rides in different ways. Except for one sentence mentioning that certain parameters of reticulocyte formation show large inter-individual variation, the study emphasizes that different individuals respond to EPO in very similar ways. The authors specifically note the similarities between men and women (though a different off score can be used for women), and the study also emphasized that they found no differences related to ethnicity.
I'm also still waiting for someone to respond to my point that there is no evidence that EPO, or any other known doping substance, would specifically enhance climbing or TT ability without also enhancing a rider's ability to perform in one day races. IOW, if a special doping program enabled a poor GT rider to win 7 TDFs in a row, why didn't he improve on his already stellar one day racing ability to sweep the monuments. I know, he focussed on the TDF, but he did ride some classics post-cancer, but he never won any.
