Correct me if I'm wrong. But the zero in the graph stands for the start of the Giro, in days yes?
So T-100, or 20 etc..is 100 or 20 days prior to the start of the Giro, and the value are plotted.
Then, at zero, or just a day/two before, there is a test. Then about 4-5 more samples drawn during the Giro, both are fairly close together, rest day range?
Seems it is pretty clear to me, if you want to dope, this graph speaks volumes on how to time your EPO mirco dosing to start raising your levels, or when to transfuse blood.
Once again, you have to be stupid and not have learned a thing, by simple pattern studying, to get caught today. It would seem, and I didn't look at the race dates to verify...lazy. But, if you want to dope, microdosing is the way to go still, and the stupid "reviewers/panel of experts" still don't know anything but what they were told my past dopers on how they doped.
So, they all seem to think that "rest days" are the key to bust people.
Anyway, there is just one value I find suspicious, and of course, lab error is the answer. That is how you get away with a violation, blame it on the lab. And if there was true suspicion, then a B sample could be done to test again.
