A few comments on the scoring system (not how to implement in Sailwave,
which I'm not too sure about). I think it might be improved.
1. A simple high point system is as biased as the Low Point System, just
in the opposite direction. I'd recommend one of the many alternative
high point systems, any of which would be an improvement in terms of
fairness.
2. The quoted SIs (presumably also repeated in the NOR since that is
what rule J1.2(13) requires) say "to qualify for inclusion in final
series results." If a boat is not included in the results then
presumably it isn't scored (that is the only interpretation I can think
of). So, that means that at the end of the series you would rescore all
the races with the non-qualifying excluded. I suspect that is NOT what
you really want to do. You probably wanted to say "shall not qualify for
trophies" rather "shall not qualify to be scored in the results" (this
is a pretty common concept). With rescoring after the last race, boats
cannot really get a true view of how they stand in series scoring until
after the last race. Even if it's fair (see below) it isn't very nice
for competitors.
I think that rescoring has potential problems in terms of fairness. It
is possible for a boat to finish 3rd in an 8-boat race but get only 1
point because the boats behind in that race don't qualify and so are
excluded in the rescoring. As a general principle, I strongly favor any
scoring system that reflects what actually happened in a race including
all the boats that "participated" regardless of whether they qualify for
the series trophies.
3. The SIs exclude boats that don't start. By the definition, OCS boats
don't start though they do finish (a boat can finish without starting).
I don't think that is a good policy. I'd be inclined to include all
boats that come to the starting area. A boat that comes to the starting
area but doesn't cross the line and attempt to start is pretty rare
while OCS boats can be relatively common (depending on how the RC
notifies boats when they are OCS). In terms of fairness, I'd use "came
to the starting area" as easy for the RC to implement yet having decent
fairness. Or, use "starters plus OCS" as I cannot think of any boats
that would be ones you want to include that wouldn't be included in that
definition.
4. Someone already mentioned the obvious problem of keying "qualify" to
a fixed number of races rather than a percentage. I agree.
5. I would never use "best x races" as that effectively eliminates one
discard for each race not held, usually due to weather (too much or too
little). You can easily have no discards when multiple races aren't
completed due to weather or for other reasons. Instead, I'd go with the
standard "one discard after x races, two discards after Y races, etc."
6. I'm not sure any scoring program can handle boats "shall not be
scored." I would suggest a better policy is "shall be scored zero
points" since that fundamentally means the same thing.
7. SI 1.4 basically says "use Appendix A to score" but that is exactly
what rule 90.3(a) says. So, I'd simply delete SI 1.4 - in general it is
not considered a good policy to repeat in the SIs the default provisions
of the racing rules that apply regardless.

Attached is the .blw for the first round of a 2 round fun summer
series.
Following is the Scoring and throw out rules from the SI.
1.1 RACES TO COUNT AND MINIMUM REQUIRED: The series will
consist of the 22 scheduled races. To qualify for inclusion in the
final series results a boat shall compete in (i.e., start the race)
at least 14 of the races. Each round consists of 11 races. To
qualify for inclusion in each round results, a boat shall compete in
(i.e., start the race) at least 7 of the races. RACE SCORES: For
series and round scoring, each boat scores 1 point for participating
(starting) and 1 point for each boat that it beats. Boats that do not
start or compete in that race (DNS or DNC) will not be scored. 1.2
SERIES SCORES: The series score for each boat will be the total
points it accumulates for its best 14 race results. The qualified
boat with the highest series score is the winner, and others are
ranked accordingly. 1.3 ROUND SCORES; The round score for each
boat will be the total points it accumulates for its best 7 race
results. The qualified boat with the highest round score is the
winner, and other are ranked accordingly.
1.4 TIES AND OTHER RULES: Race ties will be broken using rule
A7. Series ties will be broken using rule A8.1. Rules A1, A3, A5,
A6, A10 and A11 also apply.
There is no throw profile other than stated. 7 out of 11 races need
to be completed in order to get the 4 throw outs in the rounds.
14 out of the 22 races need to be completed in order for the overall
series. I think I need an expression but I'm having difficulty
understanding how to write it. I looked at the expressions in the
references but the examples don't really say what they do so it's a
bit confusing I'm not really sure how to go about writing the
expression. Any Suggestions?
