I'm not going to do the digging to find what he said ages ago but I recall that he said definitively EPO did not work on the fittest athletes who had lived their lives at high altitude. When I told him Snell and my other physiologist contact said the idea was nonsense he doubled down on the claim and said he knew better than either of them because he was in Kenya and they weren't.
By your standard, the only way Snell and your other physiologist contact can KNOW IF EPO works for particular athletes is if they are using it.
Their answer may also depend on how you phrased and framed the question. But is Canova wrong? You are fundamentally asking Snell and the physiologist to offer opinions and draw conclusions outside of their domain of knowledge and expertise. Why would they know better than a seasoned lifelong coach of many elite athletes about what EPO could improve over training at altitude? Canova may be wrong about his physiological explanations behind his opinions, but that doesn't make lab scientists right about elite performance. For comparison, read some of Lydiard's physiology explanations in his first books.
Among all those saying "EPO works" is a long proven conclusion, who has actually trained top distance running athletes like Canova has? Exercise physiologists and researchers can speculate hypothetically what could happen, and speculate the reasons why, based on artificial results in a lab setting. This has some value, but must be placed in its proper context.
