ive used phd and found it to be a great program, the settings i use depend to some degree on the amount of wind as my scope blows around a bit if its windy,
before i go too far i am using a losmandy G11 which is reasonably accurate,
i use a guide rate of .5 sidereal where possible and about 60% aggressive , i feel its better to catch up over 2 pulses rather than overshoot and do the left/right/left/ right thing. i use 1 second increments as i agree about chasing the seeing at a fast rate. all other settings are standard. ive experimented a bit with it and currently its the best for me.
select a star that is well defined but not FAT for the time length you use- its easier for a centroid on a small star than a big one.
if the winds up a bit i may go to 2x with maybee a 25% rate
you may as well use corrections in both axis as perfect polar alignment takes a while and one bump and its off (i have mine in a permanent ob so its set to go and aligned 24/7) i still use corrections in both axis
hope this helps some.
