Rankings calculations
The player rankings are a weighted average of all a player's performances, with recent matches weighted most heavily (so the overall effect of a good or bad performance decline over time). Each match performance is given a rating out of 1000, based on a set of pre-determined criteria, and these figures averaged. This means that the maximum possible overall rating is 1000, and a player gaining a rating of 900 is seen as an exceptional achievement. Separate lists are maintained for batting and bowling and an all-rounder rating is also published, which is obtained by multiplying a player's batting and bowling rating together and dividing by 1000. For batting, the performance rating is based on a combination of runs scored, the rating of the opposition bowlers, match result and comparison to the overall scores in the match. A bowler gains points based on wickets taken, runs conceded and match result, with more points gained for dismissing highly rated batsmen. A damping-factor is applied to a player's rating at the start of their career, so they do not get a full rating for their performances until they have played about 20 Tests. ==Test rankings==
