Your 20 yard pin is alright to about 25 yards. Once you get past about 25 yards your arrow will start to drop drastically. At 10 yards you should be hitting about 1.5"-2" high which would make you good out to about 25. I personally use 1 pin out to 30 yards. I know that at distances betweein 30-35 I have to aim a bit high. I have a 40 yard pin that is perfect for 35-40 yard shot.
Just to cover my own ass....I have been drinking tonight!!
