When you are in the 11-tooth cog, the effort is divided by 11. So for every cog you go forward 7.5 inches or so.
I'm really dense sometimes, so I need to clarify this at least for my own self.

I think you meant to say, "So for every TOOTH you go forward 7.5 inches or so."?

I can see that everyone, including me, understood what you meant, but I can't leave it, especially since this thread will be here for perpetuity. If I'm wrong, then I'm really confused!
