dick i would say if you are to change anything on your set up maybe try a different pair of socks not the set up on your bow ive notice that some times people start giving to many opinions on what it could be then it can make you start to doubt your shot when the deer steps out .as i took your advice on the bait for pond bass take my advice on this there is nothing wrong with your shooting or your grouping i can promise u nobody hardly ever hits the exact spot they aiming at there are so many variables wind ,angle elevation there can be alot of things that doesnt have to do with your shooting just my 2cents
