You need to set the CMP Offset. It should be 0 degrees +/- 1 degree. The number only updates at RPMs over 1500, so each time you turn the distributor you're going to have to hit the throttle once to see it change.

Look on your scan tool and look for PID CMP Offset or CMP Retard as Joe said it should be 0 +or- 1 degrees. Loosen the distributor if not in spec, turn it slightly and snap the throttle (must go over 1500 RPM). When the idle is stable look and the PID again and adjust again as needed.

You are right about your choices. Before you go too crazy though, check to see if the dist gear is worn. It happens.
