The Team Power Index (TPI) is a groundbreaking feature introduced for UTR Sports league providers and team players, aimed at transforming the way team leagues are organized and played. TPI offers an accurate measure of team strength in both singles (TPI S) and doubles (TPI D) formats and is available for tennis leagues today, and pickleball leagues in the near future.
How is the Team Power Index (TPI) calculated in UTR Sports Tennis Leagues?
The Team Power Index (TPI) assesses a tennis team's strength by using verified Universal Tennis Ratings (UTRs) from active players on the roster. The TPI is expressed as a two-decimal number, calculated separately for singles and doubles:
- Singles Team Power Index:
- Gather 100% reliable singles UTRs from the team's roster.
- Sum the top six highest singles UTRs.
- Doubles Team Power Index:
- Collect 100% reliable doubles UTRs from the team roster.
- Add the top six highest-rated doubles UTRs.
If a team does not have six reliable singles or doubles UTRs, but there are reliable ratings or estimated UTR ranges for six players, for the players with only a range, the midpoint of each player's UTR range is used for calculation along with the reliable ratings. This is labeled the "Estimated Team Power Index," which is rounded to the nearest integer instead of showing two decimal places. Reliable ratings are always preferred, and estimates are used only when fewer than six reliable ratings are available.
How is the Team Power Index (TPI) calculated in UTR Sports Pickleball Leagues?
The TPI in pickleball is calculated as a one-decimal number, and it's derived separately for singles and doubles:
- Singles Team Power Index:
- Collect singles UTR-Ps that are 100% reliable from the team roster.
- Sum the top six highest singles UTR-Ps.
- Doubles Team Power Index:
- Gather doubles UTR-Ps that are 100% reliable from the team roster.
- Add the top six highest doubles UTR-Ps.
If a team has fewer than six reliable singles or doubles UTR-Ps but possesses ratings or provisional UTR-Ps (i.e. P1, P2, P3, P4, P5) for six players, use the mapped midpoints of provisional ratings for those players with provisional rating, and combine these with the reliable UTR-Ps. This is labeled as the "Estimated Team Power Index." This index is rounded to the nearest integer, omitting the decimal point. Reliable ratings take precedence, and provisional estimates are used only when less than six reliable ratings are available.
Where can the TPI be located?
The Team Power Index (TPI) can be located within the UTR Sports League platform specifically on the following:
- League Desk: Teams with reliable ratings display a precise TPI with decimals, while those with estimates show an integer TPI. This assists organizers in seeding and managing team placements effectively.
- Creating a new league season or tournament: TPIs are displayed for each team in the league which can help the organizer create league seasons and tournaments that are more level based.
- Session profile: The Overview tab of the ‘Session Profile’ highlights the TPI for singles and doubles for each team in a session. This feature enables captains and players to gauge the strength of their team and opponents in the league, aiding in lineup adjustments.
- Team profile: TPI is prominently displayed for both singles and doubles formats. This visibility allows team members to understand their collective strengths and strategize accordingly for upcoming matches.
