SETTING UP MATCHES
Members may issue challenges to any other members in their
league. When members login, phone numbers of other players will
be visible. Likewise, email addresses are available only when
logged-in. Click the "p" (for profile) button beside the
player's name to see email address.
Players must make every effort to make and accept proper
challenges both upward and downward.
If a challenge cannot be agreed upon with a particular
player, try someone else.
The time and day for a match must be mutually agreeable.
Both players should bring a can of balls to the match and
the winner keeps the unopened can.
The 20-point system and the 15-point system
require 2 out 3 set scoring to properly determine rankings.
The 9-point system requires that a single 8 game proset be
played. The Pyramid system only requires that one player
wins and one player loses, scoring is incidental. The Quality
system only requires that one player wins and one player
loses, but margin of victory is very important in determining
rank - method of scoring should be consistent throughout the
league matches to achieve consistent results.
When scoring is required to be conventional 2 out of 3 sets,
a 7-point tie breaker (first to 7 by a margin of 2) should be
used at 6 games all in each set. The League Administrator may
decide to use "no-ad" scoring. The League Administrator may also
decide that a third set be replaced by a 7-point tie-breaker.
Scoring for the final set in this instance will be recorded as a
regular set. In other words, a game per tie-break point. If the
tiebreaker requires playing more than 12 points to achieve a
win, the final set should nonetheless be recorded as 7-6. The
League Administrator will notify all members as to the scoring
method at the beginning of the season.
If a match is interrupted for any reason, it may be
continued to completion at another time by agreement of both
players. Or the player leading the match at the point of
interruption can be considered the winner. A match is only valid
if at least one set has been completed. Both players must agree
to the settlement. If no settlement can be made, the match must
be completed or replayed at a later date - otherwise do not
enter a score. Games must be added to the score to make a
complete match - Do not enter incomplete match scores!
There are no ties in tennis. If a tied score is
entered into the TennisEngine, the player entered on the top
line is declared the winner.
When a match is won as a result of one player retiring for
any reason, sufficient games must be added to the incomplete
sets to complete the match. For example, if Jim was leading Bob
6-2, 4-0, and Jim retired, the score would be recorded: Bob def.
Jim 2-6, 6-4, 6-0. Loss of condition means loss of match.
Unless otherwise stated, all competition will comply with
USTA playing rules.
AFTER THE MATCH
The winner should enter the match results on the
TennisEngine web site from his/her personal member page. The
match results and subsequent new rankings will be posted
Otherwise the score must be emailed, faxed or phoned-in to
the League Administrator. A drop-off point may be coordinated by
the League Administrator for score sheet collection and posting
by the Administrator.
The League Administrator will make every effort to post
results from score sheets on a timely basis.
The Quality System
is great for closed leagues where a match schedule is organized by the
League Administrator. It is also very accurate for challenge ladders but
does require that at least 3 matches be played to establish an accurate
ranking for an individual. This is a great system for USTA Team Tennis or
high school conference tennis to assess talent. This is the most accurate
system for ranking players against the field, across an entire season -
based on margin of victory, opponent strength as well as win/loss records.
Sort of a "Sagarin
Predictor" system for tennis players, if you will. Any method and
combination of scoring can be used (2 out of 3 set, pro-set, single set)
Quality-based Ranking System
Please be advised that this system depends on a reasonable amount of match
data. A player or doubles team needs to have at least 3 matches logged before an
accurate ranking can be calculated.
The Tennis Engine computes player rankings based upon a proprietary algorithm
that evaluates every match played for the life of the league or conference. The
system is designed to rank each player based upon a combination of performance
(derived from match results) and activity (how many matches played and against
When a new match is entered, the Tennis Engine adjusts your ranking based on
the following factors:
Current match win or loss
Current match performance (% of games won)
The strength of each of your past opponents
Your overall match winning percentage
Your overall game winning percentage
Furthermore, the ranking of every player who has played you or your opponent
will be affected by the outcome of your match.
Winning or losing a close match with a highly rated player could boost
your ranking, whereas a close match with a lower rated player could reduce your
ranking. Decisive wins over lower rated players could be less rewarding than
close wins over higher rated players. Confused? Simply put... winning matters
the most, but after that it's all about whom you play and how close you play
The rankings are based on each player's current Index value (i.e. the
third ranked player has the third highest Index). Each player's Index is a
combination of his Strength Rating and the number of wins. Each player's
Strength Rating is viewable in his player profile.
Your Strength Rating (SR) is the measure of your ability to:
win matches against the field of participants
win a high percentage of games in all matches
perform well against higher rated players
Your Strength Rating will improve with more matches won and a better
percentage of games won. The strength (SR) of the opponents you play is also
factored into the calculation (Each player's SR is located inside his profile
along with other information).
Your SR will fluctuate as other participants compete. It might rise as
players whom you have defeated accumulate wins over other players. Inversely,
your SR might dip if players who have beaten you suffer losses.
The online league is updated every time a match is entered. Any method and
combination of scoring can be used.
