I was addressing those who read posts carefully.
Superficially, "what about Lombard?" might seem like a strong example, but when you scratch the surface, it is not.
First, did Lombard improve 3 minutes "from doping"? That is presumptuous. There are too many unknowns. Lombard signficantly changed his training, reducing his volume by half, and adding intensity, and changed his coach.
Lombard's gains are not that different to the gains Wejo made when he changed his training after college (see "Why I sucked in College"). Adapting your training to suit your strengths "works".
The example of Lombard "proves" no point because you can not prove a point by example. That is a fallacy.
Had you read my post, my point was that historically there were few non-Africans that ran faster than the fastest pre-EPO era 1980s athletes during the EPO-era (the entirety of 28 years between 1990-2017), and the few that have, did not run that much faster. If the best demonstration of EPO "working" for elite non-Africans is Cathal Lombard, that helps make the point because he was slower than the pre-EPO era performances of Lopes, Mamede, and Barrios.
When Cathal Lombard raced 27:33, he took 3rd in a time trial setup to get the Oympic Standard, 5 seconds ahead of college sophomore Dathan Ritzenheim. Lombard's only other 10,000m time at "alltime athletics" is a race where he took 4th. Cathal Lombard was never a real threat in elite 10,000m running. Similarly, in 5000m, he has two results, which were 5th and 6th place.
If Cathal Lombard is the very best non-African example, his lack of impact on elite running only helps make my point.
