A lot of people sight their bow in starting at 20 and then move back. Do the reverse of this to get a true reading of your yardage. This will deffinately close up your gaps. Sight your bow in at your max distance you feel comfortable shooting( i like 40 yrds). After this, work your way closer and sight in your other pins for desired setting. (30,20 yrds) Make sure that you hold through the shot and continue aiming at the target so you do not drop your bow arm. Shooting at 20 yrds, you might not notice mechanical problems, but as you move back they can be magnified. Hope this helps. Good luck on th eupcoming season.
