Cox-Sprague

When scoring using Cox-Sprage is it more usual to keep a running percentage
of perfection and show that in the race columns, or, just show the points
awarded in the results columns, with a final PoP in the Total column?

Why use high point scoring systems at all
(Austrian/RinderleB/Cox-Sprague)...? Presumably they are only useful in
long series, where the number of competitors changes to a large degree with
each race. Otherwise the low point bonus system seem fair and easy to
understand...

In the club series at our club, the number of boats will vary from 3 to 14 and that presents two problems for the standard low-point system. First is that a DNC is a huge usually insurmountable penalty. Second is that it is tremendously easier to place high on a low turnout day than on a high turnout day, but the points earned are the same.

We typically have six to eight race days in a series and score the series as a collection of days instead of individual races, and we are using the low-point system with one discard. The result is a strict stratification of results by number of days attended. At the trophy level, this works okay as it requires attendance and good sailing in order to win. But for people who miss more than one day, their result (within their strata) will depend almost entirely on whether they raced on high-turnout or low-turnout days and not much on how well they sail.

I've experimented with various other ways of scoring our series, but haven't found something that made it worth the effort to explain to the group and I'm not sure anyone cares other than me.

Hi Jay,

Thanks, I tend to think that if you made the effort to turn up on a colder
windy day and race, and come 3 out of 4, that 3 is as good as a 3 out of 20
on a warm sunnay day... :slight_smile: Competitors should not be penalised for turning
up... which is kinda-sorta-ish what high point scoring does, e.g. Rinderle
B, you get less points for nth place just because more folk stayed at home
to watch the football finals...

I like the idea of spreading points for 1,2,3 etc like the low point bonus,
but not so sure about the idea for changing place points depending on
turnout. We handle DNF, DNC etc by using number of boats competing in race
+ 1 as opposed to number boats in series + 1.

I agree with Colin on this one. With big boats, you have the extra
effort of getting a crew of 8 or so together at one place and one
time as well as getting the boat ready. It's too easy to not make
the effort, especially if the forcast is for a screaming
southwesterly straight off the antartic with rain thrown in for good
measure.

If the series scoring system scores that race down for a poor
turnout, then you are encouraging the stay-at-homes.

We have fixed costs for running each race so we want to encourage
participation - it's a value for money thing for our members.

Having said that, we have a race with 70+ boats in it which is 37
miles. We also have a race with 20+ boats which is 480 miles.

Currently, we just weight the long race with double points. I'm not
convinced that this is "fair".

With what the formulae people are coming up with, and Colin's
software of course, it gives us the opportunity to experiment with
previous results to get something that works for us.

This is a fantastic development for everyone and I applaude
everyone's effort so far, especially Colin's.
