I used to find if I shot 5 arrows and 5 groups my best arrow in the group and best group was the 5th on average. I dialed in as I shot. Now I find I get lazy or shift into checking my release, anchor, or bow follow through, and my groups go down hill. Often I will shot the first group well and the first arrow the best.
I plan to mostly rove when the weather breaks. Last time I went out I was seriously accurate at all kinds of ranges to 25 yd. with one shot per stump, stick, leaf..... Then I went back and started shooting groups at 20 yd., and everything went down the tubes. I have some work to do if I want to be as good paper target shooter.
I just got home and it is dark, but as soon as I get a bite to eat I will light up the target with the truck lights and see what I can do.
