I also noticed several single pin shooters set it at 25. This might make good sense. I originally set it at 20 because thats were 95 % of my shots are. I' m going to experiment this winter with this. For 30 yards I can see no problems. Its the 10 yard shot I' m wondering about. I' ll have to see what my set-up does.

Lastly, you need to practice, just as always, to make the system work, but it doesn' t take long and you know exacktly where to aim!

Good Luck!
