I shoot 1 pin too. I have markings for 20, 30, and 40 yards to adjust it too, but typically leave it set at 20. I know how high to hold to shoot up to 30 yards when its set at 20. Funny thing, which was a lesson to remind me to always check my gear, also gave me a little confidence on small blunders regarding the sight setting/distance judging. I took an archery proficiency exam which is necessary to hunt certain areas in RI. Its an easy test, you need to get 3 out of 5 broadhead tipped arrows in the vitals of a deer silhouet (sp?) at 20 yards. I had done some messing with my rest since the last time I tuned my bow with broadheads, and didnt have time to retune before the test, so I figured I'd just cross my fingers and hope for the best (dont really need the test anyway for where I hunt, just wanted to keep options open.) Well, I get up to the line and shoot, and cant believe how high I'm hitting compared to where I aimed. I grouped 4 arrows pretty high, and thought, wow, I really need to tune my bow for these broadheads. I overcompensated and sent one arrow pretty low on the last shot. Well, turns out I'm so used to shooting at 20 yards, I forgot that the last time I shot I left my sight set at 30! guess thats the equivalent of using the 30 yard pin for a 20 yard shot. Anyway, the 4 arrows that I grouped still hit the vitals. Lets me know that my bow is flat shooting enough to allow for some errors in judging distance.
