@Ioi: What is "average accuracy"? Is it sum of every bet' accuracy (for one title) divided by number of bets or is it accuracy of "average prediction" (sum of all predictions divided by their number).
If first definition is used than sum of all money in system should be constant (if average accuracy would be weighted with bets' money as weights). If second definition is used it could easily drain money from system (for example: one guy bets 100k for a game, second guy bets 200k, game sells 150k, average prediction is 100% and both guys lose money).
