And...are the numbers 0 and 00?
Ok, anyway, the reason I asked is because if they were listed as identical numbers in the book, then yes, at the 10 minute mark it should be penalized. But the way the question is worded, it says, "he notices that A6 and A7 are wearing identical numbers". If that's the case, and the book looks ok, then I wouldn't penalize until the one with the number different than what's listed in the book comes into the game.
