I don't think they follow it either. It was used to make the techs keep up with the show elements of the rides, and if an operations manager wanted to, they could call the attraction down, and be fully justified with it, thus putting more pressure on the techs to fix it. It's most likely a battle bewteen the operation and tech managers. My roommate once worked at Mummy when it was at 24 points, (all the fire out in scene 6, all the pop up mummies out, and the lights out in the treasure room). So yeah, thats a sucky day to ride Mummy.
