You are 100% correct. I was hoping that most people reading this could understand the difference and would mentally be able to negotiate the reality. (Oh man, that sounds a bit sketchy, doesn't it?).

To be completely correct, the Earth does rotate around the Sun and it also rotates on it's axis. Do either of these facts change the calculation of what the gearbox needs to have in the way of reduction? No.

Thanks for pointing out my error though, you are correct.
