not to judge your ability but paper tuning is only as good as the shooter doing the shooting, like i said no disrespect intended so please don't take any. i have seen a bow tuned by a pro and that shot bullet holes and then handed to another pro and ripped and handed to someone else and bullet hole again and so on and so forth. i would set centershot and height and try different hand positions on the grip and maybe different spined arrows until you achieve acceptable tears. gripping the bow is the number one factor in arrow flight if you ask me, just shoot your bow through paper with a high wrist grip and then with a low wrist grip and you'll see the difference right there on the paper.....
