I think I found my issue.. I chrono'ed as soon as I got the rest put on and it averaged 272fps. Started noticing the whiteish marks after that and my chrono speeds drooped to 240 average[:'(]I called the place that put mine on and they said move the cable up the bow string towards the rest more to create slack, but then adjust the cableat the HDto make sure the marks line back up. I had mine served on, so i cut the serving off and went to the cable attachment that comes with the kit. Put that on loose and drew the bow back. Everything set itself into place. I tightened it back down and chronoed.. First shot was 274, then 272, but 272 was my average again. The tech said it probably wasnt dropping fast enough, so moving the cable back up the bow string a tad causes it to load later, but drop quicker.Thus dropping it about 2inches faster. Knock on wood but mines shooting good again. I see how it does this week, but hopefully its fixed. I dont wanna tinker all season long with this. I have the biscuit for backup though LOL
