Thanks Krysta. Yes, I know there can only be 1024 steps. I wanted to verify that the 1024 steps must be present at the 130% setting and something less than 1024 steps when set at 100%. Therefore there would be advantage to always having the high rate setting above 100% to take advantage more steps and better granularity. At 100% it would be 1024 less 30% at each end direction for only 409 steps available?
