Ah Ha! This gives me a definite adjustment for my experiments. I'll try to work all threads of a single machine against a single coefficient.

I had noticed all the coefficients were multiples of 120120, but hesitated stating so. If I base my ranges such that each encloses a multiple, I should be able to set my scripts such that I can run lots of threads against those multiples and maybe even have some of my 8-thread machines working on the same coefficients.
