Anyway...
1. It's easier to beat the bio passport when you have no profile built and know when the test is coming. If you have no history then it's harder to flag someone as suspicious because their potential range is so large.
2. Law of diminishing returns, EPO is going to help a hobby jogger more than a professional runner whose RBC production is already pushed near its natural limits. So you can't conclude it would help a 7:40 runner run 7:26 or whatever.
3. Results are even more useless because there's no mention of their training over 1 month. There's not even mention of a control group.
4. Side tangent, but their VO2 max increased 6% but their 3k time only improved 3%... meaning their so called running economy decreased by 3%. Further confirmation that those values are highly overrated.
