One of the comments explains the game in greater detail than the story. Sounds like a pretty good idea. Interesting note from that commenter: "In practice the rankings are so close it involves guesswork as much as skill." In a TV world where programmers are terribly put off by actual skill or knowledge, that's the vein to strike. It's why TPIR works in ways LMAD doesn't.
