Ranking Points are calculated using the following method.

P = R x F x Q x YWF


P = Ranking Points
R = Regatta Points
F = Event Grading Multiplier
Q = Quality Factor
YWF = Year Weighting Factor

The Regatta Points:

To determine the regatta points (R): 1st = 100 pts, 2nd = 99 pts, 3rd = 98 pts, etc.

The event grading factors are now:

IFDS World Championships and Paralympics F=5 Top 90% receive points Used for the IFDS Worlds
Grade 1 F=3 Top 70% receive points Used For All Other Events

Year Weightings (YWF) are as follows:

Results in the current calendar year (last 12 months) Y=1.5
Results in the past calendar year (last 13 to 24 months) Y=1.0

Quality Factor:

Quality Factor Q = 1 + N/30

N is the number of competitors who are eligible for ranking points in the regatta and who are in the top 30 of the last published ranking list.
Q is never less than 1.0 or more than 1.5 For World Championship events and Continental Championships Q is always 1.5

Add the seven highest values of P over the last two years to determine the competitor's total ranking score.
