I think it is a failure, and has been revealed as strictly a PR stunt, on e th details of he program have now been clarified.
It could still have usefulness as a targeting tool but riders who've been dopin steadily for years (70%+ of the peloton) will give a false baseline. So for that, it's not such a useful undertaking.
It is a financial scheme, with the teams being fleeced for the bogus program. More money, with mark-up, passing through the UCI coffers. The secrecy of so many things, ProTour points/rankings, equipment approvals, etc.
The legal risk they are exposed to in a case like pelizotti is big. if you ensnare low level (salary) pros you reduce the risk you'll have one of them bring a huge suit for damages. I don't think he UCI can withstand a massive finding against them, and still be able to support the lifestyle they are accustomed to.
I also believe it is truly a sham when we've seen really questionable blood profiles, as laymen, and the UCI does nothing. Wiggans and Lance in 09 are prime examples.
Maybe the eventual plasticizer test will be the key for a while, though skirting it won't be tough given container options like steel or glass.
The UCI will not ever reveal the accounting for the program, nor the seeming drop in testing volumes, because the would provoke "where'd the money go" questions from the teams (who paid for it) and he media, who were sold a false bill of goods. It will stumble along, tripping the lowly rider here and there.
Overall, it is one in a long line of sham programs or schemes by the UCI to make money and impress an image or "doing all they can".
