USSailing has included this system to account for series over a season where not everyone registered in the series can make each race. Has anyone tried to use this system using Sailwave?
Hi,
Can you include a link to the description of the scoring system
please? It is the percentage bit that might be a problem.
I have used a high point scoring system in Sailwave in the past and
what I configured worked.
Kind regards,
Huw

Was this ever resolved, i.e., are there formulas and parameters to implement the US Sailing High Points System? I want to see how it would compare rankings to a system we use in Excel based on PHRF of the Chesapeake High Points.

I don't believe Sailwave currently has the ability to do a custom system
that includes a series "percentage of perfection" calculation. That is
what you are seeking. I suggest doing this in your Excel file as it
isn't terribly difficult IF you know Excel at all. I believe I've done
this in the past for local results and could help if you had trouble.
Locally, we use a variant as follows:
A "percentage of perfection" system takes the series points you score
(high point, low point, whatever) and compares them to what you would
have scored had you won every race you sailed in, with a minimum number
of races sailed in. Thus, it might be considered a "percentile" scoring
system (if you know simple statistics you'll know that "percentile"
basically means where you stand in a group - top 10% means 90th+
percentile).
We didn't think competitors would understand that easily so we use a
somewhat modified methodology. A true "percentage of perfection" looks
at your season and generates a percentile ranking (in a high point
system, highest percentile wins; in a low point system, lowest
percentile wins). We generate a percentile score for each race instead.
We believe we get 95% of the fairness and accuracy with none (or very
little) of the confusion. Our so-called "Sunset Scoring System" can be
implemented in Sailwave with a custom high-point formula.
After a quick look, it appears that the only really significant
difference between the CBYRA High Point system and the US Sailing
alternative is the bonus points. It should be fairly easy to redo your
current Excel spreadsheet to calculate percentages without the CBYRA
bonus points.

Art,
Thanks for the info. Can you provide the formulas and parameters for setting up the “Sunset Scoring System”? I would like to see how our current system would compare to it. I’m really looking for a SailWave solution to minimize my current admin duties on maintaining our current Excel/VBA based system that I developed.
Thanks,
Tom Owen

Tom,
I'm attaching a Word document with the language from our SIs. That
includes the official formula plus some related stuff.
Below is the text of a Sailwave User Group email from Jan. 28, 2012. It
provides the Sailwave formula plus some explanation.
Art
***************START
I believe that CHIPS is simply a straight-forward high-point system with
a formula that assigns points for each race. Sailwave can definitely
handle that (a version of CHIPS is actually built in also).
However, Sailwave cannot handle the more complex high-point systems
where your final series score is either an average of your race scores
or a percentage of the maximum possible race scores for the races you
sailed in.
My club wanted to use the Percentage Point System (simple high point
score for each race with your series score at the end being your total
points divided by the total points if you had won every race you
entered). This generates a kind of "efficiency" score at the end of the
series. [We didn't use Sailwave and our program could handle the
calculations.] But, the system is so complicated that we didn't think
competitors would understand the system. So, we simplified it by
generating an "efficiency" score for each race and then simply adding up
the scores for every race. That way it is easy for a competitor to do
their own calculations.
We have dubbed our system the "Sunset Scoring System" because our series
is the "Sunset Series" (weeknights in the spring and summer). Each
boat's score is basically the number of boats beat plus 1/2 divided by
the number of boats that start in that race. Essentially, that gives a
percentile ranking for each boat in a class. You can then multiply that
percentile ranking by some fixed number of points. We use 9 so the
resulting scores are all between 9 and 0. We then add 1 point for
entering so scores for entered boats are between 10 and 1 with
non-entered boats getting 0 points. We round points to 3 decimal places.
The score at the end is simply the total for all races and Sailwave can
readily do that.
The important thing about the Sunset system is that the middle boat in
every class gets the same score regardless of class size (if you have an
even number of boats then the two middle boats average to that score).
Therefore, class size becomes strictly irrelevant. Systems like CHIPS
give more weight to results in smaller classes (meaning that the middle
boat in a small class gets more points than a middle boat in a larger
class; and, the same for other places as well).
We use the following formula in the Sailwave high-point formula box:
1 + ((((s-p)+0.5)/s)*9)
In our formula "s" is the number of starters so as you can see it is
easy to come up with your own custom formula based on class size. Under
Setup>User interface check the box for High point scoring. Then go under
Setup>Scoring systems choose your default system, choose Edit, and at
the bottom of the Race scoring tab you'll see the boxes to enter
formulas. Put your cursor over a box and an explanation window will pop
up with some info on making formulas. There is also info in the help
file but the cursor explanation seems better and more complete to me.
The window won't stay long so just keep repeating until you can read the
whole thing.

Hi
Wondering if this high-point percentage average scoring has had any further developments on sailwave? I’m would like to implement the scoring system for a youth school sailing league run at clubs and seems to be a equitable scoring system. I’ll try the above version but if there are any other recommendations or suggestions would love to hear them.
