Eh, I don't know it's all that dire (the death of WADA). A shit-show indeed, though. Month of this crap, and all it took was the ASO threatening to ban his start for this remarkable ruling to occur.
That said, so many of these tests are remarkably qualitative and noisy - it's the nature of the beast. I'm absolutely sure in my heart that Froome/Sky have pushed to the edge and abused his therapeutic exemption. But the study which gave birth to the threshold of the test appears to be somewhat flawed.
Scientist behind salbutamol threshold admits 'terrible blunder'
The founding scientific work for salbutemol abuse and threshold came from work with swimmers. The urine is even more concentrated in a cyclist at the end of a three hour stage, which makes that threshold determination more tricky. It's not a blood test, and it's not a test detecting the presence of a man-made cytokine (like recombinant EPO) or something which should not be there (a simple yes/no), it's a threshold detection. There's a factor for 'urine dehydration' built into the test, and even with that, he was 19% over the limit. But that's frankly not very inspiring, when you consider the variation of the biology, and however they decided to factor in the dehydration.
Of course, that would have been a nice way for Sky to attack the finding, but yet we've subjected to months of reports suggesting that their defense would be that a kidney problem caused adverse drug metabolism, which is a fun argument. Not only is it likely utter horseshit, but it would be darn near impossible to re-create, even if they did do in-patient pharmacokinetic test they were supposed to do. I'm sure they'd argue that no resting test would re-create the stress of a stage. The fact that they decided to go the whole Tyler Hamilton Vanishing Twin route is pretty telling, in my opinion.
