Your effective “gear ratio” changes from one part of the chainring to another. 10 degrees rotation in one part or the crank revolution moves a different amount of chain than 10 degrees in another part.
Good idea. You may or may not like the change, but you will definitely notice it.
Yeah that's the point i was missing, that the gear ratio change happens within and only within each 90 degrees rotation.
I'm honestly surprised i didn't think of that myself given that it's essentially a sine wave.
I'll analyze per 10 degrees and get back.
