Best to do several iterations of T-point of say 26 points and run the supermodel and apply the corrections to polar alignment from the PA report. Then delete model and do a new one say 26 and keep correcting until The Sky X says its close enough.
Then do a long model and use it for pointing accuracy or even Protrack guide corrections. I think the manual states an ideal t-point model size before using Protrack.
A big t-point model does not affect star trails - polar alignment does. It only helps with go-to accuracy which with a widefield setup is not critical.
