I used to work in a bow shop and we would paper tune every bow we sold and give the paper to the customer. Some bows just don't tune well, I would try everything and I could not get then to shoot clean holes or you would have to move the rest so far in or out to make it shoot a clean hole that the customer would not be happy. I would just move back from the paper until I shot a clean hole. Man is sounds bad now but back then the boss was on you and you had limited time to set up a bow.
I think paper tuning is great along with bare shaft tuning, but If my arrows are shooting well and have good flight and I am not setting up a 3d or target bow I would not mess with it.
If the bow is shooting well and you are grouping well, don't change something just to change something.
