Same model but not specific pace.
I don’t think MJ ever tried to run the first 100m under 11sec, and the fastest first half he ever did was probably 20.8, and it was in Oslo’98 where was defeated in 44.58.
20.8 could be a better pace than the 21.1-21.3 he used when he was in his top shape, for a sub43 time target.
As for Bolt, if he runs the first 100m of the 400m in 10.2, he will finish the race walking because he can’t tolerate so much waste products in his body.
