And that is why we have science instead of opinion. I invite you to go into practice mode with a wide reciever and run the 40 10X with a stopwatch. Take the mode value or median depending on which seems most reliable (for instance in my testing 4 out of 10 times the 93 WR got a 40 time of 4.4 seconds--incidentally the 40 time of top ranked college wide recievers players). Then adjust threshold down to 0 and see if you see much of a gain in 40 time. It is really not very dramatic (at 93 you will see a mild increase).
