I can shoot better then if I shoot one every 10-20 sec. but still what weird is that I can shoot four arrowswith5-7 sec in between each shot and I can get them within 4-5 inches of each other. vs Normal 10-20 sec shooting I can get 4 arrows in a 10" radius. If I take a minute in between each shot I can get them within a 5-7" radius. I don't know figure it out. Any hints???
