From the linked thread, I have used this equation with a TT2 spinner (1200 count) and I know it does Tempest well.
--An example from the first link below: Tempest, 72 count
--if the control you use has 1200 counts per turn, the sensitivity calculation is: Sensitivity = 100 * 72 / 1200 = 6%
BUT I do not understand the information presented about Centipede and Crystal Castles.
Could someone clarify how to use the equation for a happ 3inch trackball for, at least Centipede?
thank you.
