Congratulations, dude. Probably explains why you want to fit this issue into a maths frame. Despite me stating from the get-go it's not a formal maths probability graph. It's a very simple graph. Purposely so. That way, it can be grasped by people who DON'T have a Harvard Ph.D. in game theory. You see 'em in the newspapers all the time. Simple graphs, for regular folks. But by all means, have fun with your specialty. We're fascinated with this advanced maths stuff. Really.
