So on a large white paper pie plate which is 9 inches they must put 3 out of 5 on the paper... I bet it is off hand, but still I will guess there are some that fail.

I was shooting off hand the other day at a 3x5 inch index card at only 25 yards, aiming for dead center. I was shocked when out of three shots, I missed one of the hits. Granted it was right next to the card on the 3" side, but I really did not think I would have missed the card at that distance. Try it some time...
