That's the problem though, they only released to Grappe the figures from the 2011 Vuelta onwards, so none of the ones that would actually enable us to judge more accurately.
The problem is, bilharzia is something that Chris Froome is much more likely to be susceptible to than pretty much anybody else in the pro péloton, and it is something that feeds on blood cells and would explain disappointing performance, fatigue and lowered hematocrit levels. But it is also, because of its characteristics, almost the most perfect disease of all to explain away blood manipulation. You can chuck out the old tests for Froome, the baseline is rendered irrelevant because how can you consider tests taken when he has a parasite feeding on his blood cells to be an accurate representation of what a normal level blood reading is for him? (genuine question) Therefore bilharzia is more perfect than almost any other illness on earth to explain significant changes in blood values. Coupled with the convenient time of its appearances and disappearances, and you have a recipe for scepticism.
