That gets the A axis turning reasonably fast, but Y and Z moves are still limited by the hardware settings. No need to calculate a speed for every unique job. I use the feed speed slider to tweak the speed based on the current cut. Sometimes an initial plunge needs to be slowed down but all following movement can run full speed. Full bitwidth pass VS stepover pass.

I recall having to set a couple things in the config page but after that I have not had to concern myself with how fast the rotary is turning.
It would seem to me that it would be problematic to have to calculate degrees/min based on the current diameter because in a rotary job there can be a lot of diameters and even diameters that are constantly changing. Think "oval" handle shapes.

A lot of controllers have inbuilt methods to compensate rotary axis feedrate. Mach3 does.
Almost all controllers will support G93 code.
Vectic software will output G93. Not sure all versions do.
