20yds, I am dead on with the 20yd pin, make sure to bend at the waist though. Inside 20yds I will drop the pin a bit lower. Inside 10yds, you should be using your 30 or 40 yard pin, because at that short of a distance, the arrow is still on the rise, so with the 20yd pin, you will hit about 3"-4" too high. Try it in the yard if you don't believe me!
