I see a slight flaw in your logic. You are assuming that the cover guy is also a 4.6 speedster. So If both are 4.6, they are running stride for stride with each other. But if the WR is 4.5 against a 4.6 CB, then yes, you create that theoretical 28.2 inches of seperation. But if that WR is 4.6, lines up the slot and is covered by a 4.8 LB, well you do the math.
Also, the DB lines up at lease one yard (36 inches) in front of the WR. So the WR has to be at least 0.2 seconds faster to just get by the DB.
On top of that, that's all straight line, no pads, no helmet running. Football speed is WAY different than a track speed 40 time.
Honestly, I think 40 time is one of the most over-rated statistics for a football player.
