Next turn the mount off and set the mount so the dec index mark is off. Do the 2 star alignment with no calibration stars again taking note of the pointing accuracy.
If there is a great difference in pointing accuracy you are correct. If there is no difference you are wrong.
I always thought both the offset in ra and dec from perfect were corrected for in the sky model by the 2 initial alignment stars.
Do you any "evidence" to show this is incorrect?

But just don't add any calibration stars, since the mount will then try to figure out what the real dec. offset is - and correct for the error based on where the stars really are.
