Rating system details

The top table shows you the home ground advantage used for each type of match. The second table allows you to calculate the expected result of a series given the rating difference between the two teams.

The Glicko system calculates a rating and rating accuracy for each team. A 100 point difference between teams with accurate ratings is considered to be a larger advantage than a 100 point difference between teams with less accurate ratings. Full members have the most accurate ratings because they play the most matches and Affiliate members have the least accurate ratings as they play far fewer matches.

To use the table, select the appropriate column for the type of match and locate the home ground advantage for the game and the rating difference between the two teams. The two columns on the right of the second table will then give you the percentage winning chances for the two teams.

For example, consider a Full Member with a rating of 7120 playing an ODI series against a team with a rating of 7000 at a neutral venue. The rating difference is 120 and, according to the table, the higher ranked team should have a 60% chance of winning each match.

Consider the same series being a home series for the first team. The home ground advantage for ODIs is 122 points, so the rating difference would be 242 points. According to the table, the higher ranked team should have a 69% chance of winning each match.
