Right, I know for our shooter wheel we had to average the last 5 10ms samples to get consistent data out of our US Digital 256 count encoder.
Not to mention we complicated our controller by using an equation to look up the approximate base power needed for the RPM we wanted, and then have it Add or subtract a certain amount from that based on whether we were over or under our setpoint.
After all this fuss, it has become quite reliable though.
