25 chops per second would be EXTRAORDINARY. Possible? Probably but only with super elite training. Most competent home chefs can probably do 5 Hz and probably struggle to get to 10 Hz.

The fastest button mashing record appears to be 16 Hz, so I definitely do not believe it is possible to chop with a knife in the double digits.

		Can somebody count Jacques' garlic chopping speed then? Perhaps someone younger than 80 could do it faster? https://www.youtube.com/watch?v=H3ENOZgEqXg#t=1m20s

The sixteenth notes in "Crazy Train"[1] are nominally 552 per minute, or 9.2 Hz. Moving a knife at 10 Hz is probably very difficult. I would expect 2-3 Hz is a normal pace for a skilled knife user and 4-5 Hz is showing off.

Cerebellar oscillation (in the inferior olive) gate motor control interrupt speed and are generally limited to ~10 Hz in humans.

		That escalated quickly. Thank you!
