Once in a while I shoot with a guy who used to shoot in these tournaments etc.He pays close attention to details and the deatails he will say are whether your hand placement is the same[pressure point,high or low on hand],how much different positive tiller the bow has compared to the other,center shot or not of course,but still he has a favorite that he hunts with alone.Because he says he just has confidence in that bow because he's been shooting it for years.I try to make my bows all shoot exactly the same.Same handle,same tiller,same arrow placement on shelf,and same draw length.Most times I come close but your right I think Marks that shooting one for a long time you get used to the way it shoots.
