Obviously, Asafa has not been at his best at major championships, and what comes to mind here is the work Charlie did 2 years ago about the number of races Asafa needs to get to a peak performance. But when I look through the IAAF list for 2007-2008 I see 14 and 16 races, whith maybe only 8 before WC/OG.
Asafa eventually gets there, but compare with Bolt in s-l with Glen Mills openly talking about speed from day one. Yes, Bolt ran 4 200s at the end of his s-l to get ready for Beijing, but he was already on top before he ran those 200s.
Now that I see the actual training, the whole situation starts to make sense. I can’t help wondering if the real problem of not getting to his best for major championships is that, without any MaxV work in training, the whole progression simply takes too long.
