Skipper Ranking System
Have you ever wondered how you “rate” in relationship to your fellow skippers across the country or even across the world.
A system for ranking skippers who race at different locations at different times using the same class of boat was not readily available. Therefore ideas were gathered from many handicapping systems an extensive development task was initiated and after an extensive amount of tweaking interspersed with reviews by Victoria Skippers “We now have a Skipper Ranking System”.
The Skipper Ranking System was initially developed for the Victoria Fleet but can be easily adapted to any other fleet. The goals of the Skipper Ranking System are:
A simple recording system
These goals are achieved by using:
Results from major events only
The Skipper Ranking System requires details of the event such as date it occurred, number of competitors entering the regatta and its chevron level is to be recorded. The individual skippers positions are recorded (not the points) and their sail numbers is checked against the Victoria Registry database. If the sail number is not valid the skipper is added to the database and tagged as not being registered, but used to compute results.
It is difficult to relate an event with 10 skippers sailing in Boston and 12 skippers sailing in Miami to each other. This cannot be done without some a system that awards the skippers at both events points in a standardized fashion, this is called normalization.
The first step in normalization was to create a matrix table. This table has the number of skippers on one axis, the finishing positions on the other axis. First place is given 100 points and last place with 1 point, the positions between first and last will be calculated based on any number of skippers. It just so happens that if the first place was given 100 and last place was given 15 the same logic can be used to get a set of intermediate numbers for any number of skippers.
The next step is to select a value for each level of the competition; this is referred to as the “Event Modifier” and was given a value of three. This means that the first place in a gold chevron event would be awarded 100 points; red chevron event first place would get 97 points and first place at a green chevron event is rewarded with 94 points. Last place points would be awarded to the final position in the gold event with no reduction, red would be reduced by 3 and green reduced by a further 3.
Event Modifier Table
Now for a “Year Modifier” which allows the system to devalue the points over a period of time. Two was selected for this value, meaning the points awarded get reduced by 2 each year until the result is 5 years old. Therefore a chevron event in the ranking year would not be devalued, but the previous years points would be reduced by two, then by four points, followed by six and when the results are 5 years old they are reduced by 8 points.
Year Modifier Table
The range between first and last place is kept constant for all combinations of skippers, event level and age of event, this is shown in the modifier matrix table. This table provides a positive number for any finishing position for any regatta in the five year period regardless of the event level.
Modifier Matrix Table
Therefore the normalization table first and last place points need to be 100 and 15 respectively.
Using the modifier table and the normalization table in conjunction all results used in this ranking system are related in a known way with easily understood variables.
Normalization of the finishing positions is achieved by selecting the appropriate number from the normalization matrix table. Finishing positions are across the top (x axis) and the number of skippers in a race along the side (y axis), the intersection of the skipper count and final position yields a number that is the normalized value points for that skipper, in that race, with that many competitors.
To the normalization value the modifier values are applied and a number between one hundred and one is gained. One hundred will be the winner of the national (gold chevron) event, therefore if there is only the USA nationals only one skipper could have 100 points. One point will be awarded to last place in any annual (green chevron) event that is 5 years old; therefore there will be as many ones as there are green chevron events.
As an example a skipper with a 2nd place in a red chevron event two years ago with 9 skippers competing is valued at 84.9 (89.8 – 3 – 2), 4th out of 10 gold last year = 72 (72 -0-0) and 5th out of 12 skippers at a green event 5 years ago = 55.4 (69.4 – 6 – 8). These three scores are averaged and this skipper is ranked with a 70.7 score.
