Does it have the same basic effect of paper tuning? Getting your arrow to fly out straight by adjusting your rest?
Pretty much. Just paper tuning is not as sensitive. In other words, you might get a good tear on paper but still be off BH tuning or walkback. But then if you BH tune, and go back to paper, still have a good tear, or even better, or more consistent.
Paper tune for me is just a starting point.
