Help & FAQs

When will further information become available?

We plan to communicate further details about how the system will operate in due course including:

  • Guiding principles behind the algorithm
  • Scale
  • Frequency of update
  • The length of time each result will count for within the calculation 

Although it won’t be launched until next year, now is the right time to start promoting the new World Tennis Number to ensure we provide everyone involved in tennis competition across the country with the opportunity to engage with and understand the changes being made and how they will impact them individually.

The algorithm is currently being refined to maximise its accuracy. As the system uses a highly complex algorithm to provide an accurate World Tennis Number the exact calculation will not be published. However, we will provide guiding principles to explain how a number is calculated. Once it is available further information will be shared online, at your venue, and at tournaments across the country.
