Don't know sorry, but 2 suggestions:

If using goto & camera, this works well although I'm not sure on the accuracy vs drift method:

Also I typicaly make my life easier when doing drift alignment than looking at it all the time:

I always let it drift for a specific interval, usually 5 minutes.I measure against the illuminated lines the distance of that drift. (so have only looked at it to set it going then once after 5 minutes).

I then make a correction to the alignment and start it going again, again for 5 minutes. I then measure the distance of drift again and know exactly from that (ignoring human error) how much to adjust it the second time to achieve perfect alignment. Again, Iv'e only looked through the eyepiece at the start of the 5 minutes and at the end of the 5 minutes.

I guess what I'm saying, is I tend to not look through the eyepiece much at all, when doing it the above way.
