How important is paper tuning?
I have never paper tuned my bow, my shop set it up for me, and all has been well so far. I group arrows really well with field points, I mean groups the size of a golf ball from 30 yds in, and almost as good out to 40 and 50, my arrow flights are consistent, as well as the angle they're at in the target. My broadheads shoot well enough, they fly pretty true to my field point, not even inches off in groups. I don't find it's a thing to worry about, or am I wrong? If I hit a deer in the vitals behind the shoulder, whether I hit the lungs, heart, liver, etc, it's going to die, and I can track it.
So I guess I'm asking do I need to paper tune my bow, or is it not worth the time? I just don't know anything about it so I thought I'd ask some questions.
