Can an LXD75 run a teensy bit slow (or fast)?

I've got the polar nailed (pier mounted) and get the 'less than 5'' messages each time I do an alignment. This is supported by the fact that I get very little if any DEC drift over any period of time.
However I am getting RA drift, which to me seems to indicate a slight speed issue with the RA drive.
It is possible I need to dial the RA drive speed up or down a percent or two? (haven't analyzed if it appears fast or slow yet, I just know I have RA drift).
Is this something I would deal with using the 'tracking rate' field in Autostar, or by changing the gear ratio a tiny bit?

am I crazy in thinking that the rate could need a tiny bit of tweaking? I mean...it's all digital timing with very accurate clocks and known gear ratios..how could this be?
