with the 2010/11 season, a rolling two year ranking system
is used, updated after each event. This means that instead of
updating the ranking list once a year after the world championship, it
changes after every event. Points earned more than two years previously
will be dropped as new points are added.
For seeding purposes however the list will be updated four times each
season, in October, December, February and after the World
rankings shown here will continue to be listed on a season by season
basis but will reflect the new system. For each season rankings will
be listed in the latest published order with their current ranking in
the left hand column. As the season progresses the previous rankings
will be shown in the adjacent columns so that at the end of the season,
the position at each of the cut-off points can be seen.
