How does the LTA know if the new rating will be accurate?

The ITF and in turn the founding nations (Great Britain, United States of America and France) have been working with some of the world’s best statisticians from Imperial College London to develop the World Tennis Number calculation. Their knowledge and expertise as well as their passion for tennis has been fundamental to the results achieved to date. The algorithm behind the system has been used across multiple sports and games for many years.

The system has been tested across multiple data sets, including LTA match results, to test its accuracy. The system will be subjected to further testing with live match data in the coming months to ensure full confidence in its accuracy.
