Its been a while since I did mine using PemPro but the resulting PEC curve was pretty much a sine wave.
Without it PE was already very small. I think it was something like 3 arc secs. Perhaps even less. With PEC that goes down to about 1 arc sec which is essentially pretty perfect. I get round stars at 3 metres on a 6 micron sensor and 10 minute exposures. That's with a Sky X TPoint model accurate polar alignment which is also essentially perfect.
If my tracking is off its Polar alignment not the mount. Soils can shift with different weather. Accidentally walking into the mount and bumping it hard can also throw it off so every now and then (like once a year) it may need a new TPoint model and accurate polar alignment. If I get round stars at 3 metres I of course do nothing.
I find its similar in performance to the Bisque PME, perhaps a tad better but hard to notice. Both do the job really well. The AP images past the meridian without a meridian flip so long as you won't hit the pier. The PME stops once you are in the region of the meridian.
