I recently bought a Darton Maveric bow that shot pretty good. But it was illeagle to hunt with here in ID. It had an 80% let off, & 65% is the max here. Any I had the module changed to 65%, & ever since I have had erratic arrow flight. Out of 6 arrows I would have 2, or 3, or 4 that would hit fne, but the others would be as much as 18" high & either right or left 3-4". I would seperate the accurate arrows from the others, but this time different arrows would be off. Would changing the let-off percent change my arrow flight?
