Test 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 and series played. (A series must include at least two Tests).
- A series only counts if played in the last three years.
- Series played in the first two years of the three-year limit count half; essentially, recent matches are given more weight.
- To determine a team's rating after a particular series:
- Find the series result
- Award 1 point to a team for each win
- Award 1/2 point to a team for each draw
- Award 1 bonus point to the team winning the series
- Award 1/2 bonus point to each team if the series is drawn
- Convert the series result to actual ratings points
- If the gap between the ratings of the two teams at the commencement of the series is less than 40 points, then the ratings points for each team equals:
- (The team's own series result) multiplied by (50 points MORE than the opponent's rating) PLUS
- (The opponent's series result) multiplied by (50 points LESS than the opponent's rating)
- If the gap between the ratings of the two teams at the commencement of the series is more than or equal to 40 points, then the ratings points for the stronger team equals:
- (The team's own series result) multiplied by (10 points MORE than the team's own rating) PLUS
- (The opponent's series result) multiplied by (90 points LESS than the team's own rating)
- If the gap between the ratings of the two teams at the commencement of the series is more than or equal to 40 points, then the ratings points for the weaker team equals:
- (The team's own series result) multiplied by (90 points MORE than the team's own rating) PLUS
- (The opponent's series result) multiplied by (10 points LESS than the team's own rating)
- If the gap between the ratings of the two teams at the commencement of the series is less than 40 points, then the ratings points for each team equals:
- Add the ratings points scored by the team to the total ratings points already scored (in previous matches, as reflected by the Table)
- Update the number of matches played by the team through adding one more than the number of games in the series (a two Test match series will result in the match count getting incremented by three)
- Divide the new rating points with the updated number of matches to get the final rating.
- Find the series result

Famous quotes containing the words test and/or calculations:
“It is the test of a novel writer’s art that he conceal his snake-in-the-grass; but the reader may be sure that it is always there.”
—Anthony Trollope (1815–1882)
“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
—Henry David Thoreau (1817–1862)
