8 Days, Winding & Accuracy, Advice?

[SeaDom]

Hello,

I have a PAM 564 (8 Days movement). I'd like advice on winding. I find (and I've read here) that fully-wound the watch is less accurate (mine gains a minutes over a couple of days). So I assume I should wind less, more often. Thoughts and advice on winding?

I wind my YM about 40 turns daily, which seems about right.

Thanks!
