Who Invented ICC Team Rankings?
The MRF Tyres ICC Team Rankings is a rating method developed by David Kendix to rank men’s and women’s teams playing across Test, ODI, and T20I formats.
How does Women’s T20I Team Rankings Calculated?
- After every T20I match, the two teams involved receive points based on a mathematical formula.
- Each team’s points total is divided by their total number of matches played to give a rating, and all the teams are ranked in a table in order of rating.
- By analogy to cricket batting averages, the points for winning a T20I match are always greater than the team’s rating, increasing the rating, and the points for losing a T20I match are always less than the rating, reducing the rating.
- A drawn match between higher and lower-rated teams will benefit 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.
Women’s T20I Team Rankings Calculation
- Each team scores points based on the results of their matches over the last 3–4 years − all matches played in the 12–24 months since the May before last, plus all the matches played in the 24 months before that, for which the matches played and points earned both count half.
- Each May, the matches and points earned between 3 and 4 years ago are removed, and the matches and points earned between 1 and 2 years ago switch from 100% weighting to 50% weighting.
- For example, at May 2014, the matches played between May 2010 and May 2011 were removed, and the matches played between May 2012 and May 2013 switched to 50% weighting.
- This happens overnight, so can result in teams changing positions in the ranking table despite not playing.
To determine the teams’ new ratings after a particular match, first, calculate the points earned from the match.
If the gap between the ratings of the two teams before the match was less than 40 points:
|Match result||Points earned|
|Win||Opponent’s rating + 50|
|Lose||Opponent’s rating − 50|
If the gap between the ratings of the two teams before the match was at least 40 points:
|Match result||Points earned|
|Stronger team wins||Own rating + 10|
|Stronger team loses||Own rating − 90|
|Weaker team wins||Own rating + 90|
|Weaker team loses||Own rating − 10|
|Stronger team ties||Own rating − 40|
|Weaker team ties||Own rating + 40|
- Each team’s rating is equal to its total points scored divided by the total matches played. (Series are not significant in these calculations).
- Add the match points scored to the points already scored (in previous matches as reflected by the Table), add one to the number of matches played, and determine the new rating.
- Points earned by teams depend on the opponent’s ratings, therefore this system needed to assign base ratings to teams when it started.
