Frequently Asked
Questions About Dynamic NTRP
Q. What is "Dynamic" NTRP?
A. "Dynamic" NTRP is an enhanced tennis rating system that
generates player ratings at regular intervals over the course of a season
(unlike the present "static" system that defers all rating
calculations to year-end).
Q. What is different?
A. Dynamic NTRP allows players to self-rate instead of attending
verification clinics. Disqualifications will be handled directly by the NTRP
program.
Q. How will it work?
A. Players will register through TennisLink. If they have a valid
computer rating on file in the database it will confirm their eligibility
for the team. If they have no rating on file the player will be required to
declare a self-rating before completing the registration. After each match,
the captain will enter the scores online in TennisLink. These results will
be calculated in the dynamic NTRP computer program. USTA will monitor the
ratings and inform players if they reach the disqualification level three
times based on all adult and senior matches appearing in the system.
Remember, Mixed Doubles does not have NTRP disqualification.
Q. Has the way that the computer program calculates ratings been
changed?
A. The basic mathematical algorithm has not changed. The computer still
looks at your match scores and not whether you won or lost the match.
Significant procedural changes apply in Dynamic NTRP, however. Where
historically, your final rating was a function exclusively of your results
at the highest level of competition entered, under Dynamic NTRP
"final" ratings are based 50% on your cumulative dynamic rating
entering an event and 50% on the traditional "benchmark"
calculation method.
Q. How often are "dynamic" ratings re-calculated? By
whom?
A. TennisLink data will automatically be run through a national NTRP
database, where the necessary calculations will be made. The Sectional
Leagues Coordinator will then use a limited-access feature of TennisLink to
obtain report listing any players who accumulated a "third strike"
and therefore are disqualified. The national NTRP database will run
calculations daily.
Q. Is there a difference between an in-season Dynamic Rating and
a year-end Final Rating?
A. Yes, there are several. First, dynamic ratings are not disclosed
publicly (neither to the player nor any other league player or administrator
below the section level), where final year-end ratings are published
annually and displayed on the Section’s website. Second, dynamic ratings
are expressed to the one-hundredth of a point, where final ratings are
expressed only to the one-half point. Finally, dynamic ratings are updated
regularly and based on an average of the previous four dynamic ratings.
Year-end ratings are based 50% on one’s cumulative dynamic rating during
the season and 50% on the traditional benchmark calculation method.
Q. Will my rating now change in mid-year?
A. Only if you reach the 3rd strike and are disqualified at your present
level. Otherwise you will still receive a year-end rating just as in the
past.
Q. I want to see my rating during the year. How can I?
A. You will not be able to view the dynamic NTRP ratings during the year.
These numbers will be used solely by administration to track play, identify
those clearly above level and to finally assist with year-end benchmarking
and ratings.
Q. Does Dynamic NTRP treat doubles partners differently?
A. Dynamic NTRP maintains whatever rating differential between doubles
partners that existed before a match. For example, if a 3.3 and a 3.5 player
are paired together, whatever "spread" between opponents is
dictated by the specific match results, the two partners will have ratings
only .2 different from one another after the dynamic calculation is
completed.
Q. Does Dynamic NTRP apply to Mixed Doubles League play?
A. Yes, for players who participate only in the Mixed Doubles Division.
For those who participate in the Adult or Senior Divisions as well, their
Mixed Doubles results will not affect their final rating. However, the Mixed
Doubles regulations prohibit NTRP disqualification.
Q. This system depends on match results being reported promptly
to TennisLink. How will you assure that? What happens if the TennisLink
system is "down"?
A. Peer pressure will remain the most effective tool in motivating
captains to report local league match results in a timely way. Several
sections will be establishing deadlines for reporting scores that will count
for advancement.
Q. How will corrections to match scores be made?
A. Team Captains and their players can use TennisLink to review (or
dispute and correct) match results in the time allowed by the section.
Q. Why is the validity of a year-end rating being extended to 5
years?
A. Too many players are electing to "sit out" and then re-enter
the Leagues program at a lower NTRP level, rather than abide by their
results-driven computer rating. Extending the validity period for year-end
ratings should minimize this.
Q. Isn’t it unfair to change the validity period for those
players who will have sat out two years and were expecting to get re-rated
in 2003?
A. No, rules change all the time. Notice has been available since the
summer of 2001 that this was the new regulation for 2003. We encourage all
players to participate at their established NTRP level rather than sitting
out. Many of the sections have waivers to start the 5-year history with the
2001 computer ratings.
Q. How does a player get back into the system without sitting out
for five years when their last rating moved them to 5.50 or 5.0 in the case
of Senior Division?
A. USTA NTRP Computer Methodology allows an appeal of a non-benchmark
player with a year old computer rating if it falls within .10 above the NTRP
level IF the next highest approved NTRP level is not available. Seniors may
still participate at the Adult 5.0 level. NTRP tournament participation is
another way and several of the sections run OPEN Divisions that can also be
calculated in the NTRP computer program.
Q. How will I appeal my year-end rating?
A. The same as in the past. However, be aware the appeal will only be
granted based on missing information, permanent disabling injury or if the
computer rating is less than .05 over the NTRP level and the request is to
move down.
Q. Will there still be verifiers at District/Section/National
league championship events? What is their role there?
A. There will be a limited number of verifiers at National championship
events. Their focus will be on insuring rating accuracy in same-partner
situations and out-of-contention teams. Whether verifiers will be assigned
to Sectional or District championship events has not yet been determined. If
verifiers do attend, their role will be limited to observing the Dynamic
NTRP process and providing feedback to improve that system. Verifiers will
not
gather or report visual ratings, nor will they initiate any disqualification
proceedings.
SELF-RATING
Q. How do you know that new players will self-rate correctly?
A. Historically, better than 8 out of 10 new players self-rate accurately
when attending a rating clinic in anticipation of entering the USA League
Tennis presented by Lincoln program. Actual match results will determine
whether a player self-rates too high or too low—with the prospect of
player disqualification if warranted.
Q. What do I do if I think a self-rated player is too good for
the level?
A. Captains may request a "Player Review" by the Leagues
Administrator to examine the challenged player’s match results and
resulting Dynamic Ratings.
Q. How does Dynamic NTRP work in brand-new leagues where there
are no (or very few) computer-rated players?
A. In new leagues, or leagues with very limited player history, League
Administrators will assign an "initial rating" for players in
those leagues. The precise number is established by national procedures and
tends to be at or near the mid-point for the level of the league.
Q. Can I declare a different self-rating for different League
Divisions (e.g., 3.5 for Adult and 4.0 for Senior)?
A. No. Once you declare an initial self-rating, you are bound by it for
the calendar year or until you generate a final, year-end rating. The only
exception to this is in the event of a player disqualification, where one is
immediately bound by the higher, "DQ" rating.
Q. What if I have self-rated and played four matches in the Adult
Division and then sign up for the Senior Division. Will I use my self-rating
or will the system generate a computer rating for me?
A. The system will have a Dynamic NTRP number on you from your adult
play. But you will continue with the self-rating you selected until the
"year-end computer ratings" are published. Unless of course, you
are disqualified and you then must immediately move up.
Q. During the transition year, if a player has a current visual
rating, must they abide by the visual
A. Yes. The visual as issued will be placed in the TennisLink system and
will be your official self-rating for the transition year. Self-ratings are
removed at the end of the calendar year.
DISQUALIFICATION PROCESS
Q. Do you expect more/less "DQ’s" using Dynamic NTRP
than historically has been the case?
A. Historically, NTRP disqualifications have been rare. There is no
reason to believe that will change so long as players are self-rating
accurately.
Q. What is a strike and how do I get one?
A. Each time a player’s dynamic rating exceeds the maximum tolerance
for the level, he/she automatically earns a "strike." Three
strikes—considering all matches in the Adult and Senior Divisions from all
sections in the database from Local League up to and including Sectional
Championships— and you’re disqualified.
Q. How high can my dynamic rating go before I earn a
"strike"?
A. The Dynamic NTRP system allows a certain tolerance for player
development—more for lower level players where rapid improvement is more
likely; less for higher-level players. The new Dynamic NTRP system uses the
same criteria for "strikes" that heretofore were used by
verifiers. The new methodology has not changed that standard in any way.
Q. What are the consequences of disqualification?
A. In all cases, the player is disqualified from participation at that
NTRP level. Each USTA Section will determine which of two methods the
section will follow at the local and the championship level. The effect on
Team Standings may vary, depending on when the DQ occurs:
During local league: Either the individual match that produced the
disqualification and any subsequent match played by the player OR all
previous matches played shall be considered losses.
During Championship play: If the section elects to run the
computer ratings following completion of the championship points earned by
the DQ player will stand.
Round Robin format: If the section chooses to DQ during the
championships any player reaching the DQ criteria will have all matches
reversed to 0-6, 0-6.
Single Elimination format: If the section chooses to DQ during
the championships the last match played by the player will be reversed to
0-6, 0-6.
Q. Will a player be advised each time that he/she earns a
"strike"?
A. No. Notice occurs only after three strikes are accumulated.
Q. Will I be told exactly which matches earned me "three
strikes"?
A. Yes, with notification of disqualification you will be provided with a
printout of all your matches and the NTRP level generated for each match.
Q. Who is notified in the event of a disqualification? By whom?
How quickly?
A. Responsibility for monitoring dynamic ratings lies with the Sectional
Leagues Coordinator. When a "third strike" situation arises, the
SLC will notify (a) the affected player, by telephone, e-mail or voicemail
message; (b) the player’s Team Captain, using the Captain’s e-mail
address as reported on TennisLink; and (c) the relevant District and Local
League Coordinator. Notification is made within one business day of
determination that a third strike has been received. Hard copy will be
mailed to player’s address as it appears on the team roster.
