You cannot compare the two with the data sets provided. The Giro sample is statistically inadequate to identify a true biological profile for Lance. There are only 3 data points (1 pre-race) that are taken in varing conditions (rainy time trial vs flat warm rest day). There are many factors that manipulate a riders hemoglobin levels from riding conditions and fatigue, to eating conditions and dhydration, to possible doping by the rider, to biolical characteristics of the rider. Ashenden can make the generalized statement that a riders levels should lower over the span of a stage race. This rule can probably be applied to the general population of riders over consistent eating and hydration conditions given a true statistical sampling. If the TDF ended on 7/20 there would have been an indication of drop in levels. Maybe if Lance was tested on the 7/24 -vs- 7/25 there would have been a drop in levels? Maybe if he was tested on 5/30 -vs- 5/31 there would have been a rise (the logic of most here would be he doped both races)? Everyone's biolical passport is different; hence, the passport - varying anemic or kidney issues, etc. etc. etc. You have to look at long term and statistically adequate data (not avaiable from the Giro) - One of Bordry's points, although passport is not useless.
No one is trying to establish a "biological profile" of Armstrong using the three samples from the Giro. You asked to see the Giro numbers compared to the TdF numbers, so there you are.
It is my understanding that blood is taken in the morning, before the day's stage, to reduce the number of complicating factors such as dehydration.
I'm sure we would all like to see more complete date, but this was all that Armstrong was willing to publish (and it was later taken down from the Livestrong site once questions were raised). You will note that there is zero information provided with respect to Astana's internal testing.
No one is trying to convince you that Armstrong was doping, or that blood values can only go up if a rider infuses. The point of the thread had to do with McQuaid, who believes that we CAN rely on a limited set of data points from a three week race to conclude that a rider is clean. That statement conflicts with the Armstrong values from the TdF.
