I had my AVRI set up by a pro in Sydney a few months back just after I got it and I noticed that the string winding was way different than I would normally do myself. Th number of winds on each post was massive. I guess he used an electric string winder and wound the entire length of the string as opposed to cutting the string before winding on the post. Heres a pic. Anyway, a few weeks ago I restring the guitar and thought I would try the same method. It all went well and I finished the restringing, however, ever since I did the restring the G, B and E had been going out of tune! It's been driving me insane due to he fact that I had to retune these strings constantly. Particularly the G. So yesterday I did some research on tuning and found a few comments about over winding the strings on the posts its apparently this is a big no no. I restrung the guitar yesterday back to the old way I normally do it i.e. with less winds on each post and so far so good. Jut thought I would put this info out there in case anyone else has his issue. Hope it helps. Cheers from Sydney.
