RE: in for any distance question in pin yardage
The best way to find out is to "just do it". There really isn't any reason to have a pin less than 20 yards with today's equipment. If your setup produces fairly normal velocities as most of today's bows you can set the first pin for 20 yards and only be hitting about 1" to 1 1/2" high at 10 yards. That the difference between holding the center of a bullseye and the bottom of it for practice.
Do it and see what you get. Then practice, as Arthur says. It's really a no-brainer.
