So there's paper tuning, french tuning, walk back tuning.... Why not walk back paper tuning? If you shoot bullets at 5, 10, 15, 20, 25, 30, 35, 40 yards, then you know the arrow is staying straight. Just a thought.
The way I see it, your fletchings will straighten out the arrow once it gets out past 10 yards or so anyway so no real info is being gained.
