The Test...

[Danvrapp]

When I was in "training" to become a referee, our instructor put it this way: "Four of the five deal with free throws, and the other one is obvious. Don't try to complicate things."

I suppose when you think about, what all could really be correctable relative to a free through? Well, the four items mentioned above. The fifth (obvious) one is a scoring mistake - if the scorer just added wrong and forgot to hit the button, correct it.
