So I found the updated Synscan manual for v3.35:

The new polar align procedure is described in section 11.3
This is excellent. The way they've set it up, to work in synergy with the 2- or 3-star alignment, and then iterating on a star, is logical and easier (and likely more reliable) than the Alignmaster method (although similar). They claim an accuracy if 1 arcminute after a few iterations.
Clear skies here in Adelaide, so I'll get to try it out tonight. I'll report back on how I went.
