This chart shows all 219 players who ran the 40-yard dash at the 2024 Indianapolis Combine. This outlines the outcome of various timing methods as explained in another featured story.

They were timed in "Electronic Timing" (ET) and "Hand-Held" (HH). On the ET times, players start the clock when the player lifts his hand from a pressure pad and the clock is stopped when he breaks a laser at the finish. On HH times the stopwatch is started by hand when a player makes his first move and is stopped by hand when he crosses the finish.

Michael Weinstein is the founder of Zybek Sports, which has provided timing equipment at Indianapolis since 2008. Zybek also tests thousands of athletes as young a 12-years old. He has data that shows HH times are up to .25 of a second faster than ET, depending the field condition and who is doing the HH timing. 

Results from the 2024 Indianapolis combine are shown below. These times were taken on the same runs. It shows that  of 219 runs, 157 were faster by HH. Otherwise, 43 were slower by an average of .01 seconds and 19 were the same. 

Note that Texas wide receiver Xavier Worthy, who set a combine record with an "official" time of 4.21 seconds, was credited for a 4.20 hand-held time.
