If your arrows look to be flying well and you hit what you are aiming at consistently who cares what holes in a piece of paper look like!
Like tiller, riser torque and bow geometry there are no absolutes unless everything is absolute! And believe me there are very few
(Perhaps I should capitalize that) VERY FEW bows ever built that are absolute stiff, absolute balanced and absolute in arrow travel. Just because an arrow does not tear a perfect hole at a set distance doesn't mean it is not in tune. Some of my best shooting bows won't shoot a perfect hole no matter how much you try at a set poundage and arrow spine. I know a good number of top tier target shooters whose bows don't shoot perfect holes either.
Tuning is important, but that doesn't mean you have to shoot a perfect hole for your bow to be in tune. There are not enough arrow spine options and perfect cam travel bows on the market to make that an adequate test at all. It's a nice place to start if you have poor eyesight or you shoot a bow too fast to see the arrow well in flight. But as others have mentioned above, it's only a place to start. Myself, I never shoot paper anymore. In my way of thinking that is the same thing as driving around the block just to visit the next door neighbor...an unnecessary detour and a waste of time and effort.
If you do decide to paper tune remember a few things;
*Always shoot into the center of the paper. Often times an arrow left of center will be different than an arrow right of center and each different than those in the center.
*Once you get good holes back up three yards and shoot again. Often you have found the sweet spot only at a specific distance and haven't tuned the bow at all. Shooting at least two more groups 3' back and then 6' back from your original spot will tell you if you are getting a false tear or not.
*If your arrow rest is 1/8" out of center but the tear is telling you to keep going that direction...STOP! All you will do at that point is screw up your bow, rest, arrow and who knows what next!!! Only thing you could hope for at that point is to tune the paradox and not the bow.
*If you have spent most the day pulling your hair out and you still do not have a perfect tear...grab some gasoline and a Bic and light that paper tune jig on fire! That should curb the anger enough that you don't go home and kick the dog or yell at the kids.
