Are Combine 40's accurate???

[Mistaken4193]

I was watching Amari Cooper Combine 40 on Youtube and he ran a 4.42 while Kevn White ran a 4.35 but when they simulcamed it Amari finished his 40 before White. So how are these times recorded???

they are electronically timed so best guess on the video is that they didn't get cooper and white lined up quite right since they need to match it up down to the damn millisecond.

also, I'm not all that familiar with the electronic timing equipment, is it possible to fool the sensor by maybe swiping your arm across the line before your body? if they did get the start for Cooper and white correct, is it possible white's arm caused the difference? I mean 0.07 seconds is basically zero difference.

i can't seem to find White's speed in both 40s, websites only give the fastest time. I'd think scouts would look at both and see how consistent these guys are.

White was caught in a naturally occurring Bose-Einstein condensate. As the camera was outside this localized temporal field it could not capture the quantum variance in the pi beta mazon structure giving the appearance Cooper finished first. While in actuality he hasn't finished until 3:53:24 last Sunday afternoon.
I hope this helps clear things up for you.

They are electronic at the combine, which is why a lot of kids run better times at their pro day. I had a buddy in college that was running 4.38-4.39 at school, went to combine and ran 4.55 lol

Not certain about the combine but usually electronically timed runs have the athlete wearing a RFI chip. The chip is placed at the same place for each athlete to avoid that sort of stuff.

Really? The water in the human body can interfere with RFI. I assumed the "electronic" was just a sensor. Seems that would be cheapest and easiest anyway.

They don't put the chip in their body. They attach it to their clothes somewhere.

I've seen Sandia Labs fire a series of giant capacitors using lasers timed within trillionths of a second. Timing a jock running is well within the NFL's budget. Should cost about $200 to get it accurite to the hundredths.

I know that, but the distinction doesn't matter. The water in the body can still interfere. Perhaps the location of it could be precise enough, but that still seems iffy compared to other methods.

watched it again, i think White's chest crosses earlier, the two have very different postures when running and cooper looks like he runs more upright while white has a strange posture with his head kinda back but his chest sticking out. i think that probably causes the 0.07 difference.
