hello rob, couple of things i noticed about PHD
the callibration at the beginning is critical, i usually giude at .5 sidereal ( this is set on the mount) and about 20% RA aggression(set in PHD click on the brain) as i have a reasonably smooth mount (G11) i use the lower setting you will tune yours to suit yourself. On a day with poor seeing i find the phd program cant callibrate proprly at the lower setting so go for a harder and faster setting.
You may find it willl callibrate in one axis and fail the second , what it will then do is guide in one axis only ... this could be why you are drifting away check the guiding and if needed set for force recalibration and it will do it again.
hope this helps Clive.
