With the Paramount ME with an EdgeHD 14, at f/11, FL=3911mm, mirror locked down, ~180 points mapped in TheSkyX with Tpoint Add On using supermodel to compute my model, I get 8 to 9 arcseconds RMS all sky pointing. Nothing special. I've seen people do better and I'm a bit envious. With an 8300 chip, objects land within the central box of the CCDsoft image cross hairs every time, all over the sky. Good enough for me (though I would like the 3 arc seconds RMS one guy gets with a large refractor).

Mind you, that's with things basically perfect on the mount. I have played around with how I mount the scope, how far back or forward I place it, how much DEC balance counterweight I use, dew shield on and off, how much RA balance counterweight I use and where it's placed on the counterweight bar, etc. In awkward situations with weights hanging far off axis I can get really bad pointing if I try hard enough.

ProTrack won't affect your pointing accuracy, but it may smooth your tracking. I've seen ProTrack nicely compensate for slow movement from flexure. I've found that it needs lots of points to work well. At least about 70-90 to not make things worse and at least about 150-180 to work very well.
