I will paper tune my bow only to see if the arrows right for the bow and weight. Then I go out side and at 30 yards I group tune my bow. Arrows hitting lift are right move the rest in are out are sometime a nock can be to low. A high arrow move nock up. I tune the bow to shoot good group. You may say I don't care how the arrow is flying as long as it groups really good and shoots my broadhead in the same group as my field points. People do blame the equipment to much for a bad shot and some times need to take a good look at the way they are making the shot.
