No, actually you CAN’T change that statement to some fraction of the crank revolution. You can change it to “half” because the ring has a pattern that repeats twice, and maybe “quarter” on some rings if you are precise about how you divide it up. Bit otherwise, no. 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.
