I tried a game with myself the other day. I started at about 7 yards with one arrow. if I hit in the six inch ring, I backed up about three yards and shot again. if I hit that I backed up again. If I missed, I had to step up to the previous distance. I wanted to see how many shots it took me to get back to 20 yards. It got dark before I made it, but it was still fun, and I think a good exercise.
