You're wrong on several counts there based on what is now known. Froome's daily salbutomol record on his Vuelta notes and that read in his labs urine levels showed his increasing dependence of Salbutomol due to worsening illness leading up to the AAF & not a sudden one-off amount of Salbutomol taken on the day you assume he did. That daily use with corresponding urine levels was modelled by Dr Darren Austin of Glaxo who said Froomes inhalation record despite being ramped up within WADA's rules proved the high level in the urine found could be expected. This modelling also proved 10% taking a maximum permitted inhalation amount will AAF under WADA's Salbutomol regime too. Given Glaxo doing this modelling invented Salbutomol & Dr Austin is one of the Worlds leading experts in human pharmacology, in fact Glaxo's Senior Director of Clinical Pharmacology and is telling WADA their regime is broken, doesn't really give WADA or UCI any doubt Froome is innocent, especially when before this model, WADA's own inventor of the Salbutomol regime said he messed up the testing and protocol because it only ever considered short 1 hour time frame of swimmers with full bladders not 3 week bike racing and daily inhalation.All of what we know about whether it's effective is done with certain doses under specific conditions, not always useful in determining if it will work on elite athletes at high doses for supra-maximal effort and such long-duration efforts. So we really don't know it's effective. The Froome positive seemed quite likely a very large dose that hadn't yet cleared by morning. We have no idea how much he actually took, we only know that a very large amount was left in his system at the time of testing. He could have and probably did take way more the night before.
Guys do not take stuff at that level without reason and without it having been tested OOC. Sky and attention to detail, remember? Or is that line conveniently ignored when it doesn't suit those defending him?
He took a very large dose of it on a day he needed to recover, when he'd lost time at the end of a hard stage. Why? In tests with non-elite athletes under sub threshold conditions it showed increased time to exhaustion. Exactly what he needed. Is that the reason? I can't say. But I don't believe for a second they gave it to him for no reason, and the official explanation is laughable.
