1) When? During play? During FTs?
I'm not very far out on the floor, maybe 3 feet at the most during play. During FTs, I move closer to the circle, so as to not interfere with the coach behind me who may be trying to communicate with his players at the other end.
2) HS ball? Girls tend to pass the ball from side to side more, with the ball not settling as often. Therefore, we don't rotate as much in girls' ball.
3) All I have is an Officials Manual. I don't have a women's manual and a men's manual. If you're talking about the NCAA manual, it is available online.

4) I don't know that there is an "ultimate sin." But I can think of far worse things than reaching across the paint. It's okay in theory that you don't want to reach across the paint. But the reality is that you have to do it sometimes.
