I'd be interested in a theory to describe this problem. My own interest is
in using fin tabs to assure spin at a specific rate (9-10 hertz), which
appears--to me--to be cheaper and more reliable than trying to carefully
align the fins to just the correct offset. Aligning them dead straight and
using a fin tab appears to be much simpler....
Does anyone know of such an analysis?

A homebuilt motor that appears quite reliable, and trim tabs on the
fins to get rid of the tiny amount of roll the rocket was doing.
