[FONT=fs_blakeregular]When a maul remains stationary or has stopped moving forward for more than 5 seconds, but the ball is being moved and the referee can see it, a reasonable time is allowed for the ball to emerge. If it does not emerge within a reasonable time, a scrum is ordered.[/FONT][/LAWS]
You're not wasting time, mauls aren't over if they are continuing to move, Law is precise on this if it stops moving then you allow 5 secs and even longer if you can see the ball emerging
If you blow earlier than this you're operating a foreshortening interpretation.
