Yeah, you need to be registered.
here is a snippet, hope im not violating anything:
This is the best link for an explanation as to what PrecisionPEC is and does versus Protrack,
http://www.bisque.com/sc/forums/p/9710/35396.aspx#35396
From the link the following is per Patrick Wallace and I quote.
"ProTrack and PrecisionPEC are complementary, each specializing in different parts of the same job.
PrecisionPEC eliminates the all-important high-frequency irregularities in tracking rate that are caused by the tiny residual imperfections in the RA worm drive. Protrack applies the TPoint all-sky pointing model to mop up the much slower drifts caused by such things as flexure.
Although Protrack could be made to do at least part of what PrecisionPEC does, it would require an inconveniently dense TPoint mapping run, and the diagnostic displays and tools offered by PrecisionPEC would be lacking."
There are also 2 additional links to provide examples showing how Protrack improves un-guided tracking by eliminating errors like polar miss alignment, refraction, and flexure. One is here from a customer,
http://www.bisque.com/sc/forums/p/8034/28616.aspx#28616
It should be noted that by not compensating for refraction and or tube flexure you can't expect pixel level tracking for extended periods without guiding. Extended being in many cases longer then about 1 minute with any appreciable focal length. Often times the sagging OTA will cause several arcseconds of error in only a few minutes.
Another more drastic example of what Protrack can do was posted here by me. By showing images before and after Protrack was enabled and after introducing a 30 arcminute polar alignment error to demonstrate, actually 28.5 arcminutes off the pole before and after ProTrack using 67 points and Super Model.

By employing both of these even while guiding you will compliment the overall tracking performance.
And I almost forgot What is Protrack??
