My top pin is sighted in for 20 yards and hits about an inch or so high at 10......when shooting from the ground that is. I would suggest shooting from an elevated position if you get the chance. Most shots tend to hit high when shot from a treestand and if you are already about 3 inches high at 10 yards with your 20 yard pin from the ground then from a treestand you could easily be 6-8 ionches high depending on the angle, distance, etc....

Just a thought.
