This is the table of times:
If you ignore reaction time and look carefully at 0-30 and 30-60 times, you’ll see that Mo got to 30 about as fast as Ben in their 9.79s, but went from 30-60 more slowly. Bolt also went from 30-60 more slowly than Ben and not any faster than Tim, which I think will surprise some people here.
So it’s not delayed acceleration, but extended and more gradual acceleration, which may get you to a higher top speed, but more importantly, it gets you there later in the race with less time to slow down–and that’s John Smith’s race modeling, in a nutshell.
You get this mostly by keeping your head down and accelerating for a longer period. You have to be strong enough to accelerate longer: People running 11.2 are not going to be able to accelerate as long as sub-10.2 people (thus the 11.2 people need a lot more SE work even if they use drive phase methods), your strength level has to be high enough, and different coaches using drive phase methods have different ways of getting there. MVP is using hill sprints and heavy sleds for 6 months as you see in the Steve Francis thread. HSI uses a LOT of acceleration work on the track.
