ICC ODI Championship
The ICC ODI Championship is a notional competition run by the International Cricket Council in the sport of cricket for the 10 nations that play Test cricket and Kenya, which has .
In essence, after every ODI match, the two teams involved receive points based on a mathematical formula. The total of each team's points total is divided by the total number of matches to give a 'rating', and all eleven teams are ranked by order of rating (this can be shown in a table)
By analogy to cricket batting averages, the points for winning an ODI match are greater than the team's rating, increasing the rating, and the points for losing an ODI match are always less than the rating, reducing the rating. A drawn match between higher and lower rated teams will benefits the lower-rated team at the expense of the higher-rated team. An 'average' team that wins as often as it loses while playing a mix of stronger and weaker teams should have a rating of 100.
As of 13 June, 2004, Australia leads the ICC Test Championship with 136 points, with South Africa in second place (113 points) and Sri Lanka and New Zealand tied in third place with 110 points. Bangladesh trail with 2 points.
ODI Championship calculations
The calculations for the Table are performed as follows:
- Each team scores points based on the results of their matches.
- Each team's rating is equal to its total points scored divided by the total matches played. (Series are not significant in these calculations).
- A match only counts if it was played in the last three years.
- Matches played in the first year of the three-year limit count one-third; matches played in the second year count two-thirds; matches played in the last year count fully; essentially, recent matches are given more weightage.
- To determine a team's rating after a particular match:
- Determine the match result (win, loss, or tie)
- Calculate the match points scored:
- If the gap between the ratings of the two teams at the commencement of the match is less than 40 points, then:
- The winner scores 50 points MORE than the opponent's rating
- The loser scores 50 points LESS than the opponent's rating
- Each team in a tie scores the opponent's rating
- If the gap between the ratings of the two teams at the commencement of the match is more than or equal to 40 points, then :
- The winner, if it is the stronger team, scores 10 points MORE than its own rating
- The winner, if it is the weaker team, scores 90 points MORE than its own rating
- The loser, if it is the stronger team, scores 90 points LESS than its own rating
- The loser, if it is the weaker team, scores 10 points LESS than its own rating
- The stronger team in a tie scores 40 points LESS than its own rating
- The weaker team in a tie scores 40 points MORE than its own rating
- Add the match points scored to the points already scored (in previous matches as reflected by the Table) and determine the new rating.
