2017 Year-End Ratings 



What are year-end ratings?

  • Every November/December, a “year-end” rating is published for every player nationwide. That rating is entered into the NTRP National Database as the start rate for the following year. The year-end rating is based partially on the player’s dynamic rating and partially on the benchmark calculation. The benchmarking process is what gives nationwide uniformity to the system as it calculates data from nationals, sectionals, state championships, local playoffs in that order and is averaged with the dynamic ratings for players to produce a year-end rating.?

Who will receive a year-end rating in 2017?

  • All Adult 18 & Over, 40 & Over, 55 & Over and 65 & Over players who played at least three matches. 
     
  • Those who don't have a valid computer (C) rating and ONLY played Mixed Doubles (minimum of 3 matches) will gerenate a Mixed Exclusive rating.

When will year-end ratings be published?

  • The scheduled release date is December 1, 2017.

What if I am already registered on a 2018 Championship Year team?

  • Players who are already registered on a 2018 Championship Year league team (early start league) whose published rating at the time of registration was in level may continue playing on their current team and may advance to the state championship with that team at that level unless their NTRP rating reaches the disqualification mark for that level.  If the players 2017 Year-End rating publishes at the disqualification mark for that level, they will receive a letter via email with notification they must stop playing on that team immediately.

Tennisrecord.com and/or Tennisleaguestats.com indicated that I would get bumped up (or down), but I didn’t. Why?

  • The USTA posts the official NTRP ratings on our website, TennisLink, located at tennislink.usta.com. This is the only public website where official NTRP ratings authorized by the USTA are posted and can be obtained.
     
  • The USTA is aware of other sites that suggest they provide NTRP ratings or player statistics and skill analysis. Any alleged NTRP related information available on these other sites is not endorsed by the USTA, may not be accurate and cannot be relied upon. USTA is in the process of taking all appropriate actions against these sites available to us.

Which matches are not used in the NTRP calculations?

  • Combo Doubles, Tri-Level, Flex Leagues, 70 & Over, Mixed (with exceptions).
    NTRP tournaments are also not used in ratings calculations.

How are ratings calculated?

  • The dynamic ratings for 18 & Over, 40 & Over and 55 & Over Adult League matches are calculated every night in a national database in New York. After all National Championships, benchmarks are factored with the final dynamic rating to calculate a year-end rating.
     
  • Mixed Doubles (for those who ONLY play Mixed Doubles) and Adult 65 & Over League data is included during the final calculation of year-end ratings.
     
  • Ratings are actually calculated out to the 100th. So where you may see 4.0, the system sees somewhere between 3.51-4.00. Ratings to the 100th are not published.
     
  • While calculating ratings, for both the dynamic and benchmark rating processes, the computer calculates a rating for each match played. This is based on dynamic rating at the time of the match for you, your partner and your opponent(s), as well as the score of the match. The computer calculates a rating for every player in each match. At the end of the year, the computer combines the ratings of your match results with the benchmark ratings and then includes any matches you may have played in the Adult 65 & Over League. After all of these have been included, your final year end rating is determined and published.

YOUR RECORD (TOTAL WINS AND LOSSES) IS NOT A FACTOR. 

  • What is important and what is used in the calculation is the score of the match and the strength of your opponent. A singles example: You play a computer rated person that is a strong 4.0 player (3.90) and you lose the match, 6-4,6-3. Then you play a weaker 4.0 player (3.52) and win the match 7-5, 6-4. When the computer calculates your ratings for each of those matches, your match rating might actually be higher for the loss to the stronger player than it is for a close win over a weaker player. This is because the computer is measuring you against your opponent and this is determined by how close the match is according to the score. When measuring you against the stronger player, even though you lost, your match was competitive. Though you might not have been as strong as your opponent in that match, you were fairly close and would receive a strong match rating. When measuring you against the weaker player, the match was a very close one, only one break in each set was the difference. You and that player, on that day, were fairly close in performance, and you would receive a match rating close to, but above, your opponent's.

Does Dynamic NTRP treat doubles partners differently?

  • The NTRP Computer Rating System maintains whatever rating differential between doubles partners that existed before a match. Example: Team A (3.32 player and a 3.50 player) win 6-1,6-3 against Team B (3.08 and 3.42). All four ratings will change based on the score of the match but the partners’ differential or spread between each other’s ratings will not change. Team A will maintain a .18 spread and Team B will maintain a .34 spread between the partners.
