rybo post just about sums it up for me, I am no expert bow wizard but I have a member on this forum to thank for the knowledge that I do (Big John) and its enough to get my bow tuned by myself to the point I want it, the deer on the other hand, every few years everything seems to change, its not so much the deer as the enviroment. Several years ago a narrow funnel behind my house was the "gimmie" spot and had constant use, now its rare to see a deer there. This past season my "gimmie" spot was gone due to timbering and a new county jail being built adjoining the property. As soon as I get a good pattern on the deer something changes.
