Well, I know "4" is a set for left-outside hit, "5" is for right-outside, "1" is for quick hit right above net next to the setter, while "2" is for "semi-quick" that is a little higher and off than "1", and "3" is like the second "2" and is a little further behind "2"... oh "10" is a set for back row hit. Any other calls and numbering that you want to share?
