Agreed Robin, it SHOULDN'T.
I will reject and start again any 3 star alignment with an alt/az error greater than 1° (as reported by the synscan post-alignment), so I know the alignments were ALWAYS sub-degree, and that should only introduce a SMALL amount of Dec tracking.
Previously, I had noticed that everything was fine until the guider calibration sequence was initiated - and I had Dec and RA guiding on. Then, running it's N,S,E and W calibration is when the "fun" would begin.
I have no real idea what was going on, but suffice to say that removing the crud from the Dec gears worked.
