If the ball hits the bottom edge without hitting the face of the target it is a no rep. The middle of the ball (part that sticks out the furthest) can hit the bottom face of the target but not under the lip. That's how I've seen no-reps called pretty much everywhere, including when I was at the masters. When we asked them how high the targets were they didn't answer.
