The bow will more than likely not go out of tune but your shooting ablility may haha!!! Don't want to knock your shooting ability because I don't know how good you are. But just like they always say practice makes you better and if you set the bow down for awhile you may have lost a little bit of that consistency. Archery is all about replicating what you have previously done. One of the best proffesional archers in the world is told by shooting coaches that he has terrible form BUT he is extremly consistent making him extremly good. Hope this helps
