For a hangtime calculator the error (actual vertical-measured) derived from a parabolic translation of the equations of motion is
(c^2-8*c*h)/16h, where c is the amount of knee bend (compression below center of mass) and h is measured height. For h=40 and c=6 (even if he compressed 6 inch), the error is -2.94, so he would still have a legit 37 in

Awesome video, thanks for sharing. What brand & model of force plate did you use???
-
I concur that this is a legitimate 40" he was in the air for slightly more than 27/30th of a second.
-
WOW he even put his hand up in the air, he probably would hit 43 if he just rocket jumped
-
This shit is bananas!
-
Holy shit that was nice
-
how long did u train before u got to this milestone?
-
see thats the problem with hangtime alculators.the second jump he lifted his legs to improve the hangtime so the calculation would be higher. he lifted his legs higher they wernt straight
Running, are you dumb? That's a clean, legit 40 inches. In the video he was at a standstill...
