I stayed on the stamina screen for so long because I was sending a pic to my friends.

Decided to retime my run using Filmora X just to make sure I got it right, because the time I claimed is based solely on my reaction time to press the Split button. Turns out I was a bit faster than what I claimed. With "faster" I mean "a negligible 10 frames faster, that still technically count but not really". I can't really complain if it gets rolled back to 320ms, tbh.
