“But if you are playing a team that has a rating considerably higher than yours, you get more for beating them than they would get for beating you. The reason this is important is because, unlike a lot of other leagues in many other sports where everyone plays everyone else over a fixed period, there is a lot of inequality in the Test fixture list,” he explained.
“Therefore you needed a system that removes any bias from the mix of fixtures, so that the ratings of the teams aren’t unduly influenced by whether they have played more or fewer matches against stronger or weaker teams. There’s no secret formula. If you plug in the result of a series and the rating of your opponent, that gives you the points you score for that series. The total number of points earned divided by the total number of matches gives your rating,” he said.
“It’s like a batting average. If you have good innings your batting average will go up, if you have a bad one it will fall. Similarly, your rating will move up if you win and fall if you lose, with the size of the change depending on the strength of your opponent,” he said.
Kendix, 45, who has been the official scorer for all internationals at Lord’s since 1995 and a member of the ICC Cricket Committee for the past five years, said he became a scorer because he was hopeless at cricket.
