Ax, none of the players (1, 2 and 3 in your example) won as they picked Tmapa or Tampa Bay instead of picking Tamba Bay. On a serious note, it didn't make much sense to me that 24-0 pick was better than 17-6. It all becomes game of luck that way. Even Proud's idea was a little different. The Differential idea might be a little complicated but makes more sense. People who are making a prediction don't need to stress much, we will do the calculation. This also gives more sense to the prediction. In your example the prediction thought it would be a lopsided win 24-0 while it was a almost a close game 17-7, and still the guy won..so unfair. With the Differential idea 17-6 would've won the match, rightfully so. What do you think AX? What do others think?
