@Carl.
Remember Mr.Average is not an average of peoples scores, but an average of peoples predictions which has then been run through as if he were a competitor... this is why in general most people will be below him in points.
For example if there were only 2 people in the competition, if one of them over predicts all the time, and the other one under predicts, the average of their predictions would do well in the middle, but both of them could be a long way behind the average.
You did do better this week than the previous 3 weeks though Carl. so far you have achieved 19th, 20th, 21st and week 4 you are 14th.
