Still learning Tpoint as well, but another sneaky test for PA (other than what a Tpoint SuperModel reports) is provided during PEC capture.
After loading and fitting a PEC log within TheSkyX, I see a definite drift (slope down to the right) in RA over time. So, my PA is off as well. Confirmed during unguided work, I can't go for too long. Further confirmed by the big trackbox size that I must use to actually collect PEC data!
Other users stay right around that PEC curve centre line with no drift. I look forward to that
