I saw the pic.I am a little concerned about the arrows pointing different directions.It might be the bail causing it.
When you walked back,you did use the same setting on your sight didn't you? 20 yard pin?
I would still group tune,this will tell you how you are shooting and should bring the bow into the correct centershot with you.
I like to check things with paper,I can get my bows tuned correctly with centershot and spine and then check paper and it will usually yield a good tear.If it doesn't,there is a problem,regardless of what many think.Notice I said check with paper,I don't tune to paper.
ohbowhunter,the idiot you ran into trying to paper tune your bow was tuning to paper.Not tuning the bow,arrow,spine and shooter.
Ituned a bow 1 time that had to be set 1/2 high to get good tear,it took 3 spine sizes up to get the arrow set level and shoot good paper.For targets,it isn't that big of an issue but for fixed blade heads,it becomes an issue.
