The number of "counts" per rev depends on the way you decode it.
Counting rising and falling edges on both channels will give you 480 counts per rev
Counting rising and falling edges on one channel only will give you 240 counts per rev
Counting only rising - or falling - edges on one channel only will give you 120 counts per rev

Correct me if I'm wrong but would the 480 counts be for 4x, 240 for 2x, and 120 for 1x? Also, I have been told that 4x deciding is needlessly complicated for what I am doing (maintain RPM on a shooter with a PID) would you agree with that and if so what do you recommend?
