First of all WELCOME! This has been a good place for me to learn and it could be for you as well.
What is your bow? How is it set up? How fast does it shoot? There could be many variables. I know a few guys that only use one pin for 10-20-30yd shots. If your bow is fast enough that is all you need. Thats why there are so many single pin sights available. Tell us a little more about your rig.
