interesting..that means to compare to elite sprinters, you need to subtract the reaction time.
maurice green's WR 6.39 60m is a 6.28 without reaction time.
his 50-60 was 0.83, 40-50, 0.86 and 35-40 0.46.
so thats 2.15s
which gives him a 4.13 35m time. (38.3yds)
there must be something in the fact that the timer starts at the athlete's movement, as opposed to the athlete reacting to the gun..
basically everyone except Greene is slower than the WR 60m sprinter.
additionally, the top dozen track and field sprinters are all slower than the top dozen NFL players....
something is very dodgy about those figures.
