Just clarifying; because of the difference in gearing between the two cyclodial gears this goes from a powered zero to moving the difference between both "stages" every revolution.

The gear ratio should be the same as if this were a standard 2 stage cyclodial gearbox with the same number of teeth, as I understand it.

100% right.
