Since no-one else has stepped up to the plate, here be this year's ranking prediction competition. I've made some changes to the rules in order to try and make each player's performance have an equal contribution to your score regardless of their current ranking, and to mitigate the effects of injury/retirement:

1. Predict the ranking of the current top 10 GB mens players at the end of the ATP tour on 5th Nov.

2. Predictions have to be made by 9th Jan.

3. The points scored for each prediction will be the difference between the higher of their actual rank and your prediction and the lower of the two, as a percentage of the lower. e.g.

You predict a rank of 150 and the actual rank is 200, you score (200-150)/200 = 25%

You predict a rank of 200 and the actual rank is 150, you still score 25%, not 33%

Using percentages means that the larger fluctuations in the ranks of the lower ranked players won't dominate the smaller movements of the better ranked players, so we can include Andy in the game.

4. The winner will be the entrant the lowest average percentage error.

5. If any player fails to play in 18 tournaments (e.g. due to injury or retirement) the ranking points they score in the tournaments they do play will be increased pro-rata and they will be assigned a ranking equal to the highest ranked player in the ATP rankings with that number of points or fewer. If player finishes unranked, they will be assigned the same ranking as the lowest ranked player.
