I've got centershot at 25/32" and the nock is 3/16" above square. The cam needs to be in proper alignment, you can get a diagram from technical support at Mathews. This setup gives me slightly nock high and left tear up close which by eight feet will be a bullet hole and stay that way back to 5 yards. Once this bow is tuned it is whisper quiet. But out of tune it gets loud.
