This is a good read and, incidentally, I recorded the nearly exact same time for Dorin’s run’s on my watch as the reported hand held times listed in the article. I remember recording 4.51 on his first one and then getting a text that the official was 4.40 (so I figured that’s great for him) then I got 4.41 on his second run (which I think I mentioned earlier in this thread).
This makes sense when you consider the simul-cam footage that showed Dorin, Mays, Holiday, assuming the footage starts at the same time for each runner’s take-off, where we can see the separation at the tail end of the 40; however, I would have liked to see Dorin’s second run, which was his faster attempt, placed in comparison to the other runners.
The fastest I’ve clocked Dorin on my watch at the facility is 4.3high (I recorded it so I’m able to re-time it when watching the video).
Interesting that the individual operating the laser was getting faster times, on occasion, then the hand timers. This has NEVER happened to me when I use our existing Brower system and a stop watch at the same time to compare my hand held time to the manual start/beam finish Brower. I’m usually a tenth faster on my stop watch.
