ATP RANKING SYSTEM, written by Clark Coleman (clc5q@uvacs.cs.Virginia.EDU)

Here is the complete information about the computer ranking points on the
IBM/ATP Tour.  Players are ranked on the basis of their best 14 results in

Main Draw Bonus Points

The following points are awarded for defeating a player ranked #1 through 200
or a doubles team ranked 2 through 400. The match must actually be played,
not a walk-over.

You compute the sum of the doubles rankings of the opposing team
members (which could only be 2 if they were tied for #1) and thus
there is no #1 listed, and all the rankings are twice as much as the
corresponding singles rankings.

Qualifying Points
-----------------
A player or team gaining entry to an event through a qualifying
competition shall receive one half the points awarded to a second
round loser in that event as bonus points, in addition to whatever
points they actually earn in the event. Lucky losers do not receive
these bonus points. There are no bonus points awarded in the qualifying
event itself, regardless of opponents' rankings.


Ranking Penalty: Withdrawals After 12 Noon Eastern Time USA
-----------------------------------------------------------
If a player withdraws from an event after 12 Noon Eastern Time USA on
the Friday before the start of the event, he will be penalized in the
rankings by one event per 12 month period, e.g. he will be ranked by
his best 13 events instead of his best 14 events after one such
infraction, by his best 12 events after 2 such infractions, etc. The
penalty shall remain in force for 52 weeks after the time of the
infraction.  This penalty shall be waived if, within the first 3 days
of the main draw, the player is examined on-site by the tournament
doctor and deemed incapable of competing at a professional level.

 -10-             WTA - Virginia Slims Rankings (Women)

        VIRGINIA SLIMS RANKINGS POINTS (WTA), written by
  Natasha Austria (U58476@uicvm.uic.edu) and edited by Shun Cheung

The women's computer rankings are determined as follows:

Points are awarded based on how far a player advances in a tournament.
Bonus points, based on the rankings of opponents beaten in each round,
are added. The only exception is the Virginia Slims Championship, where
a player gets the higher between (1) ranking points she gets based on
the method described above and (2) her ranking point average going into
the VS Championship (described below) plus any bonus points she receives
there.

The total points awarded for each tournament played within a 52-week
period are added & then divided by the number of tournaments played in
that same period (minimum divisor of 12 tournaments: if one plays 11 or
fewer, her points will still be divided by 12). Unlike the men's system,
all the women's results count with the exception of Federation Cup,
Olympics, & exhibitions.  Of player must have played in at least three
tournaments in the last calendar year to obtain a ranking.

The current ranking system awards points based on the tier of a
tournament as well as the type of draw (the number of players in the
main draw in a tournament).

 -11-           WTA - Virginia Slims Bonus Pool Points (Women)

(Formerly Kraft Tour Points)  Written by Shun Cheung (shun.cheung@att.com)

The Virginia Slims Bonus Pool points are used to determine the eligibility
for the year-end Virginia Slims Championship at the Madison Square Garden
in New York City (the top 16 qualify) and each player's share of the bonus
money pool. Otherwise, they are of little significance and should NOT be
confused with the ranking points.

The Virginia Slims Bonus Pool points for each player is the simple sum of
points she receives from all tournaments in a calendar year. For each
tournament, they are solely determined by how far a player advances; there
are NO quality (bonus) points for beating highly ranked players.

Since Virginia Slims Bonus Pool points are a simple sum, some players whose
rankings might not be in the top 20 but play a lot of tournaments can earn
enough points to quality for the VS Championship. Moreover, since every
player starts with 0 point at the beginning of a calendar year, those who
play a lot of tournaments at the beginning of a year may rank very high in
Virginia Slims Bonus Pool points during that period. This distortion tends
to disappear towards the second half of the year.

Below is a table showing how many points are given for the different levels
of tournaments.

The ATP computer rankings on men's singles tennis began in 1973.  I have
verified this list with several different sources. In particular, Clark
Coleman (who used to post frequently in this group) checked it against an
official ATP Guide and it is generally correct. Some of the dates may be
off by a day or two because rankings don't always change on Mondays (e.g.
the final of an event is delayed to a Monday or Tuesday because of rain,
etc.), hence affecting the calculation of the durations, which may be off
by a week. Otherwise, this list is correct to the best of my knowledge.
Those who find errors in this list please let me know.
