Mine are set at 20, 30, 35, and 40. I don't have much drop between 20 and 30, but enough to make a difference between 30 and 40.
I was just playing around with mine like I said, and all my pins are as close together as they will go. I was just kind of guesstimating the yardage because I was shooting and stepping back and forth until my shots were on for each individual pin. Then on the ground I marked where each pin was on target at, and ranged it with a range finder. Just came out to be 23, 29, 35, and 45
