Ray,
You seemed pretty stubborn about me being wrong about the move distances being different between East/West
The issue with PEMPRO is not the difference between East and West moves, but I don't want to get off topic.
According to your PDF when you had mismatched guide and PEC rates you observed drift.
The report does not say that. The mount reports its state as slewing periodically and momentarily, but there is no change in drift. I assume that because the PEC divisors are different than the guide divisors, the mount reports its state as slewing at each PEC correction, but there does not seem to be any other side effect.
Have you tried measuring drift with mismatched guide/pec rates?
I did measure the drift with the same PEC curve and different guide rates and the drift in RA does not change (approximately 1 arcsec/min).
Hopefully someone else can measure their residual PE/drift at different guide rates using the same PEC curve so we have more than one sample.
Eric
