I agree with Derek, try to keep it simple. I do a walk back tune. Start around 10 to 15 yards and tweak your rest till your BH's and FP's are hitting the same spot and keep moving back, making very slight adjustments along the way till your about 35 to 45 yards, depending on your comfortlevel. And leave it at that. Now if you don't get the results your looking for, thinking about moving your nocking point and other things (arrow stiffness and weight ect..) may come into play... Thats just my two cents. Good luck and let us know how it turns out
