long time lurker first time poster...
i thought i would share my experience with 40 times as i have heard lots of 'what is the difference' remarks here this year
back in the day i ran a 4.65 40 in collage...
at the time that i was clocked at that speed another runner ran a 4.57
let me tell you guys... that difference is about a yard
for corners and recievers thats the differnce between open and coverd...
.08 of a second is all it takes at full speed to get open
