This is false. https://imgur.com/a/Xs4EZq7 screenshot from program I use to edit out the clip of the actual WR. Submitted clip was inserted to the timeline.

It prob has to do with the clipdownloader and youtube that make it a little longer since this is about miliseconds

@VirtualCoins actually I just retimed your chest% run, it is 0.610 not 0.420

btw the .42 in your editing program probably means frames, not ms. 42 frames at 60fps in .672ms
