Platform Tennis Index

What is the Platform Tennis Index?
New rating system adopted by the APTA for leagues

The APTA has teamed up with league website to offer Platform Tennis Index (PTI), a new feature for all APTA members who play in APTA leagues. League administrators, team captains, tournament directors, and teaching pros will find the PTI to be a valuable tool for the sport.

What is a Platform Tennis Index (PTI), and what does it mean?

A player’s PTI is a number from 0 to 80. It is similar to a golf handicap: better players have a lower PTI.

  • An 80 represents a player who has never played paddle before and has little racquets experience.
  • A 0 represents a highly-skilled player who is competitive at the national level.
  • It is possible to have a negative rating.

How do players get an initial PTI?

There are four options to set a player’s initial rating:

  1. Use match data from prior seasons.
  2. Set an initial PTI based on a player’s division/typical line number.
  3. Have a club platform tennis professional set it.
  4. Play in an APTA tournament that uses Live Scoring.

In most cases, Paddlescores can use your historical match date to generate PTI for an existing league. The APTA and Paddlescores will help get a new league up and running.

How do I get a PTI for players at my club/in my league?

To get a PTI, your league needs to use Paddlescores (powered by Tenniscores). For leagues that require APTA membership to participate, everyone in the league will have a PTI. For leagues that do not require APTA membership, APTA members will have a PTI. Players who are not APTA members won't have a visible PTI (although it will be computed for them and ready to access when they become an APTA member).

How does a PTI adjust?

PTIs are dynamic and adjust after match results are posted. The PTI algorithm uses the match outcome (win/loss and games won) and the relative strength of the teams playing to determine the adjustment.

Player A (a 20 PTI) and Player B (28) have a match versus Player C (24) and Player D (30). Team A/B has a rating of 48 versus Team C/D with 54. The team with a lower rating is favored to win the match. If Team A/B wins (the expected outcome), PTIs for A and B will decline a small amount and PTIs for C and D will increase by the opposite amount. If Team C/D wins (an upset), PTIs for C and D will decline by a more significant amount while PTIs for A and B increase.

Large changes in PTIs are achieved through upsets or lopsided victories between closely-matched teams. A heavily-favored team cannot improve its PTI by feasting on weak opponents.

What are the benefits of players having a PTI for leagues and club pros?

  1. PTIs are used to prevent lineup “stacking” in league play. For example, the top divisions in the Boston Men’s League require that teams order their lineups by PTI. Line 1 must have a lower PTI than line 2, which is lower than line 3, etc.
  2. PTIs can be used by pros or team captains as an objective measure to help evaluate player placement for club teams, often a delicate process.
  3. Tournaments: PTIs are now being used in Boston to create tournaments for all different levels of ability. With PTI thresholds determining eligibility, every player in the country would have an opportunity to compete at their appropriate skill level.

APTA PTI National Championships

This coming season, the APTA is launching a series of Men's National Championships for players of every skill level. Eligibility for each of these new tournaments will be based on a player's Platform Tennis Index (PTI). (See the preliminary schedule below the Q & A.)

Q: Why just Men's tournaments?

We plan to launch the same set of tournaments for women as soon as we have more women's leagues using the PTI system.

Q: How do these tournaments fit in with "B" Nationals?

These tournaments will replace "B" Nationals for men. The top players in "B" Nationals the past few years will likely find the PTI 10+ Nationals as a similar skill level event. Women will keep the "B" and "C" Nationals tournaments for this coming season.

Q: How does eligibility for these tournaments work?

Each individual's PTI must be at or above the designated tournament's # in order to be eligible. Example: in order to be eligible to play in the APTA PTI 25+ Nationals, both players must have PTIs of 25+.

Q: Can I play in more than one PTI Nationals?

Yes - as long as your PTI makes you eligible, you can enter more than one.

Q: Will the PTI Nationals be located in the same city every year?

No, the plan is to have each PTI level tourney rotate to a different region every season (similar to the main National Championship).

Q: What will the format of the PTI Nationals be?

Most of these tournaments will be one day events with a max draw of 32 teams. 3rd set super tie-breakers and double deuce scoring (similar to Team Nationals) will be used to insure getting the event done in one day. The Semis & Finals of each event will be held at the main hosting site with dinner/beverages served for all participants to enjoy.

Q: How does Team Nationals fit in with these tournaments?

These APTA PTI Nationals are being scheduled to take place the three weeks between the APTA Men's & Women's Nationals (in Darien) and the APTA Team Nationals in early April. The plan is to have the APTA Team Nationals in Chicago again this year... and to use PTIs to determine the different levels of play for the Men's divisions.
