The high speed ratchet reduction system... I've never seen anything like it... very, very cool. And since I've never seen or worked with anything quite like it, the following comments are based upon my impression of the animation and description of the mechanism... those with more experience or insight are invited to add to or correct them.

I suspect since the input would be just under 2000 RPM that the jerks would be fairly small. At an output speed of 20 RPM for instance, there would be 100 "jerks" per revolution... not so different from stepper motors, perhaps... as the output sped up, well, at 400 RPM there would be five "jerks" per rev. A bit more coarse, but considering the speed, perhaps not a problem.

It would also have to magnify torque in inverse proportion to the reduction in speed... or else give off a LOT of heat. This is because power = torque x rpm. If you reduce the input speed without increasing the output torque, then you have a whole bunch of power that has nowhere to go... which leaves me wondering a bit about their claim of "constant torque across the speed range".... this must require changes in the speed and/or torque on the input shaft.

P.S. The real questions are... how efficient is it, and does a CIM mount to it easily....
