Except the exact situation outlined above, in which a person generated bills that they otherwise wouldn't have needed, for the sole sake of having more bills "paid on time".
So, how does one get over in gaming this metric? Take out a lot of credit accounts once your credit is good and then default on them? What's the end game where they come out ahead? See prior comment about the bank job... that's just called having and ruining your credit.
