I've always wondered why P's are written into a stage, and then the timer "warns" shooters about them as they shoot the stage. I've seen some shoots where a timer warns shooters about the P and then forget to tell a shooter or two. That really "chaps my hide" as they say. Now if a shooter requests to be reminded before the beep, I'm ok with that but if you tell one shooter, you need to tell every shooter.
As a follow up here, if a shooter forgets to take a stage prop ( a money bag ) from station to station for instance. My thought here is that you rob a shooter at a chance to earn a P (being sarcastic).
