On PHD2 it has several display options. One is a very good graph showing RA and Dec errors plus the correction commands to the mount, the other is a stats board which shows the current average PE error (that 's the .62 I was referring to).
I used the guide assistant which determines guide exposure length and min/max moves. It actually recommended 14 seconds. The AP1600 PE is super smooth so if PA is very accurate (which mine is) then that gives the really super low PE number of .62 arc seconds.
Long guide exposure is basically saying the mounts PE is really good and only needs a minor correction every now and then.
