As far as the tuning bit goes, that wouldn't be a problem for me. I always keep mine in Open G. Keeps the songs a little less boring when you do a different improv-style break during the set intermissions for songs (instrumental verses). I tend to only put it in standard if the singing of the song requires it, and even then I usually just switch to my mandolin. My twelve-string goes out of tune, with no exaggeration, in less than a minute. It's too much of a hassle to use it.

But, for future reference, how would you time all of your sets? Just record them individually and add that? That'd take up a lot of time...Although, I guess it's good practice.
