The WTN algorithm uses match results from 2016 onwards to calculate a player’s number. When players compete, it analyses the pre-match rating of both players. The algorithm then predicts what it thinks the outcome of the match will be. Players’ WTNs will change depending on the actual match score and how it compares to the prediction. The more results the system holds, the better the algorithm will understand a player’s ability, and therefore, its “confidence” in the player’s Number will increase. Match results are analyzed at a set level, meaning the algorithm takes into account each individual set as its own result.
Yes, match results are analysed at set level, meaning the algorithm takes into account each individual set as its own result. The WTN algorithm compares its score prediction with the actual score to determine what a player’s specific rating should be.
