I just tried using the tap function on a guitar metronome, and on that fastest part where the camera is focusing on his cranks, it's reading 185-194, but that also depends on how accurately i'm tapping his cadence into the metronome, since he is going so dang fast and the camera is choppy.

Edit: it looks like my tapping sucks. I just remeasured it and yes, it's approx 160-170
