But aren't the degrees for BTDC measured BACK from TDC, hence a spark firing
at 10 degrees BTDC would occurr *before* a spark at 5 degrees BTDC, therefore
5 deg is more advanced (along the stroke) than 10 deg BTDC.

OK. I'll try and turn it more, but it sure seems like its at a 'limit'.

I was worried about a worn distributor shaft as well, but the timing marks
are rock solid with the strobe, as is the dwell angle.
