DYNAMIC NTRP & THE LEAGUE PLAYER

 For a number of years, the USTA has envisioned a league program in which a new player to the program could self-rate without verification, register for a team and begin to generate a computer rating by playing matches against other players who already had a computer rating.  This would create a number of positives for the program: 

1) ease of entry 
2) ease of administration
3) better NTRP ratings 
4) more growth in existing leagues  and
5) better customer satisfaction.  
 
Dynamic ratings require that all returning league players are entered into the computer with their most current hundredth-of-a-point computer rating at the beginning of the league year.   New players to the program will generate a rating beginning with the first match in which they compete against a player who has a computer rating.  Visual rating assignment will no longer be an integral part of the rating system.
 
What are the advantages of Dynamic NTRP?  Well for starters, new players won’t be required to attend verification clinics thus reducing the hassle and cost, and allowing ease of entry.  Players can look up the ratings of friends and players with whom they are competitive (via the internet) and use that information in addition to the on-line level characteristic descriptions to self-rate and enter the program.  The current subjective method of having that self-rating approved by verifiers will be gone.  But with the loss of verification comes a greater responsibility on the individual player to self-rate correctly.  While the subjective method of disqualification by verifiers at the championships will go away, the computer will assume that responsibility. 

In a purely objective, mathematical function, the computer will designate a player to be disqualified if the player reaches the disqualified level three times (for all matches played in adult and senior divisions prior to the national league championships.  Keep in mind that the disqualified level for each NTRP level of play has an improvement factor built in.  Players who “ring the bell” and reach the disqualified level three times within the local league season will not be allowed to advance with their team to championship competition. 

Depending on the sectional option, either the last match or all previous local matches for the disqualified player will be considered losses.  Thus, players clearly above level who try to “sandbag” their self-rating and play down will ultimately hurt their team.  Dynamic NTRP computer ratings will include more results in the rating calculation as they are calculated from one large file in which ratings from all levels of play reside.  Thus a player who plays at one level in the senior division and another in the adult division will have all of his results considered in the same calculation, making for better and more current ratings. 
 
The USA League Tennis program regulation booklet contains fewer regulations due to Dynamic NTRP.  There are no longer be verification procedures or NTRP complaints.  Player profiles are not be required.  Ratings are purely objective and players are not disqualified based on one match in which they “were in the zone.”   Because of the non-subjective manner in which ratings are derived, end of year appeals are only allowed for borderline ratings (.05 above level) or for players with permanent debilitating injuries. 
 
The TENNISLINK system allows for quick on-line data input and retrieval, and players can quickly access other teams’ results and league standings.   Being a team captain no longer requires mounds of paperwork or money collection.  The TENNISLINK system incorporates a national database in which all USA League Tennis program ratings reside and which is connected with the USTA membership database.
