thats what im thinking... after this season Im gonna do away with it. I chrono alot and get funny speeds from 240 up to 270. Whether thats the chrono or not I dunno, but it groups good. Just the chrono spikes and the contact I see makes me wonder if they are related. Im just very picky about the perfect setup. Everyone says the timing cord has to be perfect. After adjusting it about 50 different ways I cant find the perfect spot I guess. I might have adjusted it 100 times since ive lost count. I know it comes up fully about 1inch before full draw so thats not the issue. The bad thing is, I cant shoot more than 62 pounds or it really starts leaving a mark.
