Yes, of course you always do whatever is possible to obtain the LEAST amount of feather contact with a normal shelf...but in the end your still launching arrow's with relatively high fletching off a shelf and even when tuned the the best degree possible...that pesky bottom hen fletch is gonna rub on some part of the shelf(other than the extremely narrow shelf's I mentioned) and some feather wear in arrows that have been shot a good deal is normal in even the best tuned setups. Sometimes arrow spine needed to have the least amount of shelf contact can actually be too weak for consistent accuracy...of course too stiff a spine will always result in excessive fletch contact. I'd agree that arrows showing fletch wear after only a few days of shooting is not normal.
A few years ago, I was shooting an ACS-CX that was undoubtedly the best tuned off the shelf setup that I've ever shot. Bareshaft flight was amazing(even out to 100yds) and I actually won a couple local tournaments shooting bareshafts, but that was also during the time that I shot 5-6 hrs 5-7 days a week and the bottom hen feather's was well worn after only a week or so of shooting.
Not trying to dispute your post Bradd, only pointing out that blanketed statements can sometimes only be correct up to a point. In the end all you can do is bareshaft tune, powder the shelf or use lipstick to check for contact, then eliminate all the fletch contact possible by rotating nocks.
