The latest Open Match Race Rankings is released yesterday at the ISAF web site. There is a nice calculation behind these rankings. In a nutshell, it is the sum of your best four scores from the most recent two years. Each score is weighted by two factors, one based on the Grade of the event and the other based on the date. Scores from the most recent year (i.e. events occured within the last 365 days) are multiplied by 6, while events dating from 365-730 days are multiplied by 3. The grading factor is easier, it goes from 1 to 3.5 for Grade 5 to 1 respectively. So in the end the formula looks like this for each event: Score x Grade Factor x Year Factor. Given this formula, it's easy to see that during your first year it's quite important to have lots of races so that you can have at least 4 good scores under your belt. These will be multiplied by 6, giving you a boost in the rankings. For me, the numbers look not so bad so far.
