For correction, I spread polish on speed 1, and increase to 6 once distributed. If its hot in my garage, I'll either decrease my work area to 1 ft X 1 ft, or only increase the speed to 5 or 4 (ok, only 4 once). I decrease the speed because I've found I get less dusting with 106ff.
When using polish to bring out the shine I use a Gray pad, spread polish on speed 1, and bump to 4 or 5. I also work the Gray pad faster (about half the pad width a second).
When applying wax, I spread on speed 1, and increase to 3.
I'm happy with the results, but I do it as a hobby. I haven't ever charged, and so far I'm happy to say I haven't given any refunds
