Heard on ESPN if we convert bolt times over to a college style 40yds dash it would be around 3.8 and he would cover the last 40yds in about 2.9sec. I think his 40yds could be even faster considering BJ ran a similar time and Bolt is faster then BJ.

ben had a better start

Harder surfaces now but Ben was 3.80 to 30m and Bolt has gone 3.78.

Yep, I agree. Bolt has one of the best starts in the business.
