I agree with Johnch, shoot less if you know you hit tight groups at the yards you shoot at then you know that your bow is sighted in. so If you have a crazy flier you know its you not the sights/bow. Usually after I sight in my sights and I can hit groups at any yards that I decide I will hunt at than the way I practice is put myself in a tree on on my knees just any position I might find myself in while hunting than I shoot only one arrow at my 3d target if I hit the kill zone great if I miss than I collect my arrow and keep practicing in that position until I can hit the kill zone in every position. makes sense because when hunting you are only going to get one shot at your animal so I like to know that my form is consitant in any position and on the first arrow that I shoot. Good luck, Also when I shoot a crap load of arrows I find that if I have some bad shots I end up consitrating on my form to hard and it just gets worse, so when you practice have fun and things always seem to go well for me, honestly the more I think about form the less consitant it gets. when I have fun out there it all seems to come into place.
