RE: Confused
One thing I know a lot of folks who are new to the sport make are that if they shoot one or two groups bad they immediately move thier sights or start tweeking their bow. Each person has good days and bad. And your shooting form can change based on your physical or mental state when shooting.
First as noted above, do a paper test with some of your arrows, This is done by setting up a large piece of paper ( Newspaper works ) pulled tights between two braces of some sort. Place this set up just a couple feet in front of your target, then PReferably with a bare shaft, shoot through the paper from just 4 - 5 yard away and ensure your shafts are going stright through the paper. if there are large tears in the paper in any direction, you need to adjust your rest or knock point to the point where you are tearing only straight holes in the paper. Once this is done and you set up your sights to group well, then don't move them for a couple days of shooting. See if there is a difference in where you groups go based solely on your form and grip, verses moving the sights everytime a couplearrows are in a different place.
