Given that the original data was super-modeled, and one is trying to refine those numbers, after a recalibration you end up with numbers that really don't tell you if your adjutment moves actually helped. Am I making any sense here? So, it seems that if you want to compare super model numbers before with super model numbers after the only way is to start a new model from scratch.

If your aim is to improve PA, and you want to preserve your 200 point model, yo will need to save / export your model, i think as a dat file, then start a new pointing run which will clear everything (it wont delete your save data). Run your 50 modeling points, make the recomended adjustments until your happy with it. Its not an iterative approach but you may want to run 2 maybe 3 runs. Make sure you get pointing samples low down.
Once your happy with your PA, clear the model then import your saved 200 point model and super model it. Now you need to do a recalibration run using the portable mount option. Choose about 20 points from the SCP area up to Dec 0, over to the west and to the east, and scater some down near the horizon. once the points are captured, press finish, no super modeling required. Your Done, and although the scatter plot and RMS values may not look like or as good as your 200 point data, the mount will be using your 200 point data.

The PA report wouldn't necessarily show an improvement but you would know that it was actually better.

Thats it, although 50 points for recalibration is not necessary, 20 is fine. 6 is what the manual says i think, but 20 has been mentioned on the forum.
