Sevo, i’m not saying you cant prepare a sprinter using traditional RT methods, however check the improvement of PR’s which Brimma made, perhaps Australia’s most ‘recent’ credentialed 200m runner in just missing the 200m Final in Atlanta (5th in semi), from the time he left JB to the time he finished up with Cliff Mallett, Youngy can give you the specific time improvements. It may surprise you!
I do not dispute his improvement for a second and I agree with you that he was the best recent 200m runner from Australia but he too would not qualify as an elite athlete…having run 10.28-10.30 fastest in 100m.
