RE: Average Shot Distance
Average over 15years is probably 15yds.
And remember, grouping is only good if the group is in the kill zone. A 2 inch group that is 8 inches from the bullseye means nothing, except you can consistently miss[8D]
I always limit myself to 10yds close that my exceptable target range. For instance, I can shoot good at 40yds with a compound, keeping all shots in the kill zone, but I limit shots on game to 30 yds. That helps to minimize the jitters you'll experience on stand.
