Find the points earned from a match
Each time two teams play another match, the rankings table is updated as follows, based on the ratings of the teams immediately before they played. 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, then points will be as follows: If the gap between the ratings of the two teams before the match was at least 40 points, then points will be as follows:Example
Suppose Team A, with an initial rating of 100, plays Team B. The table shows the points awarded to the two teams for 9 different initial ratings for B (ranging from 20 to 160), and the three possible match results. This illustrates that: * The winning team earns more points than the losing team. (Unless the ratings are more than 180 apart and the weaker team wins − highly unlikely.) * Winning always earns a team 100 points more than losing, and 50 more than tying. * The total points earned by the two teams is always the same as the total initial ratings of the two teams. * The points earned by a winning team increases as the initial rating (quality) of the opposition increases, within the constraints of earning at least its own initial rating + 10, and no more than its own initial rating + 90. A winning team therefore always earns more points than its initial rating, increasing its overall average rating. * The points earned by a losing team increases as the initial rating (quality) of the opposition increases, within the constraints of earning at least its own initial rating − 90, and no more than its own initial rating − 10. A losing team therefore always earns fewer points than its initial rating, decreasing its overall average rating. * In a tie, the weaker team usually earns more points than the stronger team (unless the initial ratings are at least 80 apart), reflecting the fact that a tie is a better result for the weaker team than the stronger team. Also, the stronger team will earn fewer points than its initial rating, decreasing its average, and the weaker team more points that its initial rating, increasing its average. * For a given result, the rule of how the two teams' points are calculated changes as the initial ratings change, from being based on teams' own ratings when one team is far stronger, to being based on the opponent's ratings when the teams are closely matched, back to being based on own ratings when the other team is far stronger. However, despite these sudden changes in the rule, the number of points awarded for each result changes smoothly as the initial ratings change.Find the new ratings
* 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.Historical rankings
This table lists the teams that have historically held the highest rating since the T20I rankings was introduced. In April 2018, the ICC decided to grant full T20I status to all its members. As a result, ratings of leading teams since 2018 have been considerably higher, and cannot be directly compared to those before that date.Summary
The summary of teams that have held the highest rating by days, are:Top ranked teams in the ICC Annual Rankings every year
