Got a better answer for you after talking to a few folks.
At pro day there are in the neighborhood of 20 to 25 people there with stop watches between scouts, agents, and coaches. Talking to someone who was in the crowd that day Peter’s times ranged from 4.45 to 4.59 on the different stop watches. The way the UL coaches get an official time is they just pick 4 people randomly and use an average. So by doing that he left with an official time of 4.57. So it looks like the 4 “randomly” picked times happened to be those on the high end.
In the last 2 months working with a trainer he was timed 3 times and they were 4.48, 4.43 and 4.40.
FYI. They were in the indoor facility which is none to be somewhat of a slower track.
