My rms is usually around 0.4 arc sec’s on the dec and 0.8 on the ra and averages at 0.7 total. It rarely goes over 1. I think you need a pretty regular wave in the ra drive for pec to work. My ra errors are mostly a bit random so pec training hasn’t done much good on my setup. Having the mount on a pier makes good polar alignment easy, as well as increasing payload capacity.
