Probably EPO does not work as well on them because their mitochondria is smaller and less dense than Africans, like Renato always says about the best Africans. I am serious about that though. 30-40 yrs ago Japan had a load of 2:09-2:12 marathoners and even if everything remained the same, EPO should have progressed them by 4:00 en masse.
I don't understand this part of your post. I thought that Canova established that EPO does not work in Africans living at high altitude ....
