There has been a "known fact" that training more always implies having better results. Assimilating the training is, at least, as important as the training itself, and you can't do that without proper rest.
Track and field isn't an equation where if somebody does 9.58 in 100m (it's still unbelievable for me to say that time!) training 3h a day, he will do 9.10 training 8h.
In Bolt case he is not only really well trained but also he is a superior human being in athletic terms. People that are training way harder than he is, will never be close to his PB.
PS: yeah, I think that he will run under 43 seconds in 400m...
