Before changing any of the settings on your bow, nock point, brace height, etc., I would suggest that you try experimenting on changing the way that you grip this particular bow. What I have found through trial and error is that my grip on the bow changes where my arrows consistently impact on the target. I primarily shoot a longbow, but occassionally (just for fun) grab an old recurve I have to shoot for a bit. Because of the way that the risers are configured both bows require a different grip placement and pressure to hit where I am looking. Don't take this as advice, I'm not qualified to give it, but one thing that I have learned from Moebow is that instead of looking for problems with equipment, the most vital part of the shot is the form that is used to hold, draw and release.
Just my thoughts.
