Match Hub Grading changes 1 October 2019

Hi Club Captain

This email is to advise of a change in how Gradings are calculated in Match Hub. As of September 30, Match Hub will change to using Points based promotion instead of Wins based.

On the surface not much will change and there will still be 12 grading bands as at present. However there will be different Grade points bands for males and females.

This means that there can be one unified Grading List and mixed gender matches will count for points without having to make any adjustment to the female player’s grading.

Rationale for change

  • The reason for the current Grade Wins based grading was to encourage participation in competitive tennis by emphasising the reward for winning, rather than the fear of losing. However a lot of feedback has indicated that the pressure to get a Grade Win at all costs has created downsides especially in areas where it can be difficult to get a match that counts for a Grade Win.  Match avoidance and defaults in consolations are not new issues but the added pressure of Grade Wins seems to be a compounding factor.
  • Other  factors have been the difficulty in applying the Grade Wins formula correctly because the sequence of matches was extremely important, as well as the clustering of players at the bottom and top of grades. 
  • Seeding for tournaments will now be easier and should be better as there will be less players on the same points at the top and bottom of Grades.  
  • Mixed gender matches, which have been a popular feature of the Grade Wins system, will still be possible and even easier to manage for tournament organisers.
  • The unified Grading List means that mixed gender Grade based leagues and tournaments will be simpler to organise.
  • Doubles gradings have been difficult to get right in the Wins based system due to the volume of matches played and variability of levels in partnerships.  This has meant players being promoted too easily and above their true level and the effects have then compounded. 
  • As more shorter format tennis is played there will in future be potential to count the results for points in a manner that would have less impact than in the Grade Wins system. 

There will be a Cutover at the beginning of October to convert all players to their new points position. All players will have the same Grade as before. Matches from October 1st will be processed under the new rules.

Grading Recalculation
The Grading recalculation will still run twice monthly – as at 15th and last day of each month. 
Players gain or lose points for each match depending on their relative points in the Win/Loss points adjustments table. Basically the bigger the difference in relative points equates to more points to be gained.   

Grade Promotions. A player moves up a grade automatically when their points reach the next grade band level. Similarly a player moves down a grade if their points drop below their grade base, however a 2 month period of immunity will apply to any player who has just been promoted. All players will also get 2 months immunity from downgrade as of Sept 30.
