Dear Mark,
Physics etc was never my strong point but geometry states that 360degrees is a circle? Where does Tenyu get his 630 degrees from unless of course he does more than one [ in Aikido terms ] rotational movement?Having said that why would anyone want to rotate more than 360 degrees anyway?Ice skaters may do multiple rotational movements but these are just 360 degrees multiplied by the number of rotations they do.I have yet to see a compass/protractor that can draw /measure 630 degrees. Cheers, Joe.
To answer your questions to the best of my ability:

Yes, there are 360 degrees in a circle. A degree, in this case, is a measure of angle. Of course the graph is labeled "x = time". Now, given a known angular velocity, you can associate time and angle, but there is no indication that this has been done in the graph. I suspect that Read Sensei had a verbal discussion that went along with the graph.

630 degrees does imply more than one full rotation around the circle.

Respectfully,
Mark Kruger
