North American Doubles
Ranking Criteria
(Revised-September
19, 2006)
As North
American doubles tournaments have proliferated in both number and participants,
there has been an increased need for a ranking system to both recognize
accomplishment and importantly to help tournament directors seed their events
more accurately. Accordingly, a formulaic ranking system has been created to
include both Canadian and United States events.
The
rankings will be presented for North America in total and for the United
States. The system has the following characteristics:
�
A player will obtain a ranking if he/she wins a minimum of one
round in a main draw sanctioned event. Rankings take into account the best four (4) results of a
player over the past two (2) years from all sanctioned approved play (includes
play in different divisions). To obtain a ranking in
the MEN�S OPEN, a player requires a minimum of 3 results.
�
Rankings
are based on total accumulated points from the four best results over the
course of a two-season revolving cycle. Points are allocated by tournament
results:
Champion = 60
Finalist = 45
Semi-finalist = 30
Quarter finalist = 15
Round of 16 = 5
¾ Playoff = add 5
Consolation Winner = add 5
Points for the current year are valued @ 100% and @ 75% for
the previous year. The total accumulated points are divided by 4 to determine a
player�s current standing. A player may be ranked in more than one division
provided he has played at least one event in that division over the 2-year
period.
�
Each draw of each age category will be weighted by age and depth of
draw.
�
AGE WEIGHTING commences at a value of 1.1 for OPEN, .88 for Age 30
years, and .64 for 40 years. All older age categories will be weighted at 80%
of the value of the previous division. For example, points earned in the 55�s are worth 80% of the
same points earned in the 50�s. This process enables players moving up a
division in the two-year period to carry results forward into the new division.
�
STRENGTH OF DRAW Weighting. Each division is assigned a �strength of draw� factor
based on the rankings of each player as of the start
of the tournament entered in the draw. That
factor is multiplied by the points earned in the division. All sanctioned
draws commence with a .5 weighting and are subject to the following increases
if players ranked in the top 21 are entered up to a maximum of 2.5 except in
the case of an Open draw with Ranked ISDA players the maximum allowed weighting
is 3.
#1 & 2= player= .2
each .40
#3 & 4=players=. 175
each .35
#5 & 6=players= .150
each .30
#7-11=players=
.1
.50
#12-16 players=
.05
.25
#17-21 player=
.04 .20
Total 2.00
Therefore in a draw where 21 of the top
ranked players on the North American Ranking system all played, the draw would
be weighted as a 2.5.
ISDA players with no established NA
Ranking, will use the most current ISDA Ranking as of the month of the event, with
the following weighting:
#1-6= .25 each 1.5
#7-12= .20 each 1.0
Total 2.5
�
The Ranking Committee retains a degree of discretion to account for players/teams
with an established history but insufficient data. From .20 to .35
may be added in the case of a wild card player who does not or has not played sufficient
events. The maximum of 2.5 strength of draw weighting factor per event (except OPEN
with ISDA players which is 3.0) may not be exceeded by the inclusion of wild card
players.
