San Francisco Season Championship and Long Distance Series Scoring Rules
At least 50% of the possible races must be sailed by a boat to qualify.
Once you have raced in 50% of the total races you begin accumulating throwouts. The larger percentage of races you do the more throwouts you get. You recieve one throwout for every race you do beyond 65% of the total, so once you hit 65% (of the season end total of races) you're score can never go down by racing.
Your score is computed by dividing the total number of boats you beat in each race plus one by the total number of boats you have sailed against. For instance if you only sailed in three regattas where there were 5 total races and you scored a 2nd of 17, 8th of 17, 3rd of 5, 12th of 13 and 3rd of 13; your score would look like this:
If you don't sail in a regatta or part of a regatta (DNS or DNC), it
does not get counted against you. This means that you don't get a 0/12 if you
could not make a regatta or a race in a regatta where there were 12 boats sailing.
A DSQ results in a 0 / (# of boats) for that race added to your score.
A DNF will be averaged between the remaining boats that didn't finish a race. For instance, in a race where 10 boats started and only 5 boats finished, the 5 DNFs will be given a 3/10. This number is reached by adding up the remaining points that could have been assigned if all boats finished.
-------------------- = 15/5 = 3
In the event that redress is granted in a race for purposes of season scoring, a boat shall receive either the position assigned by the committee in the particular race, or if the race was not finished by the boat they will have their average score for all races sailed in the series applied to the race in question. For example, if a boat has a ratio of 45/100 in races sailed in the series, and was granted redress in a race that 10 boats started, they would be given 4.5/10 for that race. The points assigned for each individual race will be rounded to the nearest 0.05.
