Of course it could be spun faster at a smaller size to take advantage of the additional contact and acceleration time.
Hrmm... interesting thoughts.

Why 360 degrees of rotation and not 1440 degrees of rotation? The latter would make for a taller cylinder. Or, some amount of rotation between those two numbers. Funnily enough, if you want to pursue an Archimedes Screw, you can look at a couple of designs from 2009, Lunacy, and modify them from orbit balls to frisbees.
