It was more to do with the periodic error, although the total PA for my HEQ5 was quite low, but changes to it were sudden thus guiding required frequent corrections at 1.5 arcseconds per pixel.
As I mentioned before, I could notice a significantly smoother PA with AZ-EQ6 and when I transferred my rig from HEQ5, AZ-EQ6 shifted it around at ease comparing with HEQ5.
Moving from HEQ5 to AZ-EQ6 was a bit like changing from a small 1.5L car to Ford Falcon; it might not be the most sofisticated car out there but it makes for a smooth ride on a highway.
