The ISAF grading criteria for events will be applied. Details can be found here.
Points towards the world ranking are calculated as follows:
X = F x (N+1-Rank)/N
X = Ranking scored by a competitor at an event
N = number of competitors
F = Basefactor (200, 100, 50 or 20)
World Rankings from 2011 onwards
The points of each competitors best 5 events within the last 12 months will be added separately for each discipline. The actual ranking position will be based on the sum of ranking points. The competitor with most points is the first.
The ranking list is a continuous system. After 12 months the points are deleted.
