Guys this is all in the manual.

Tpoint's Polar Alignment Report corrections relate to the True Pole.

Use that to get it down to a level where any further adjustments on your system simply make it seesaw back and forth and then turn on Protrack and you will be good to go.

To get a good PA you really don't need many points at all, 10-20 is plenty, the extra mapped points are needed for Tpoint to correct for other terms of mechanical error and for Protrack.

PE has nothing to do with the polar alignment and pointing corrections - PE is usually much less of an error than the refracted pole to true pole error ie an arc second or two for PE verses an arc minute or two for atmospheric refraction shifting the optical polar alignment.

Good Guiding will take care of all of this in any event without Protrack
