What is Zero Pivot in the Hinge Action Education Drill?

Thanks for the response, Daryl.

Lots to chew on in your thought-provoking reply, many of which go beyond my to-date understanding. I've got lots more to read and understand.

Candidly, this is the first I've seen anyone refer to the "Pulley". For my benefit, can you briefly describe (or point to) what you mean? Given that my questions are related to the Basic Motion drills, I can only assume that this doesn't involve a wrist cock (accumulator #3?).

(Correct me if I'm wrong but the wrist cock doesn't get added until Acquired Motion (?)....)
