Oriental Dinghy Club Long Series Scoring System Review Bill Kirsch 4/2/2011

Why are we here? Decide Which Series Scoring System to use – Using standard / accepted systems – What variations within standard to use eg: Throw-outs, Qualifying requirements Not here to: – Discuss Individual race scoring – TOT remains – Invent a non-standard system

Long Series Scoring Alternatives Low Point System High Point System Average System High Point Percentage System

Systems Used In Past 3 years Low Point 5 years Average 1 year High Point 2006 – 2008, 2010 – Average 2009 – High Point 2003 – 2005 – Low Point

Low Point System Advantages: Most recognized Most easily understood Fully automated Excellent for a regatta Disadvantages: Missing a race puts boat at significant disadvantage Missing multiple races, more than the allowance for throw-outs, can virtually make you non-competitive No weighting factor

High Point System Advantages: Recognizes difficulty in beating more boats by awarding more points (weighting factor) Fully automated Disadvantages: Not easily understood when viewing results Missing a race puts boat at significant disadvantage Missing multiple races, more than the allowance for throw-outs, can virtually make you non- competitive

Average System Advantages: Easily understood Recommended by US Sailing Does not penalize for missing races Disadvantages: Does not provide weighting for number of participants each race The series results are not automated and require spreadsheet maintenance by scorer Does not lend to having throw-outs

High Point Percentage System Advantages: Recommended by US Sailing as best alternative Provides weighting for performance Does not penalize for missing races Fully automated Fairest system Disadvantages: Not used in ODC before now Not easily understood at first

US Sailing Long Series Alternative Scoring Systems The Racing Rules of Sailing contains two scoring systems, the Low Point Scoring System and the Bonus Point Scoring System. Those systems are appropriate for regattas held over a weekend or a championship or race week held over several consecutive days…... … US SAILING presents two additional scoring systems that some fleets and clubs may find preferable for long series that extend over a month or even an entire season. They are the High-Point Percentage Scoring System and the Low-Point Averaged Scoring System…. Both the High-Point Percentage System and the Low-Point Averaged System assign a race score to a boat only for those races in which she competes. Under each of these two systems, she can miss some of the races without penalty provided she sails in sufficient races to qualify for the series. Therefore, she is not placed at a disadvantage if she cannot compete in all the races.

Average System Advantages: Easily understood Recommended by US Sailing Does not penalize for missing races Disadvantages: Does not provide weighting for number of participants each race The series results are not automated and require spreadsheet maintenance by scorer Does not lend to having throw-outs

Average System

High Point Percentage System Advantages: Recommended by US Sailing as best alternative Provides weighting for performance Does not penalize for missing races Fully automated Fairest system Disadvantages: Not used in ODC before now Not easily understood at first

NOW FOR SOME REAL DATA

Low Point System - Real Data

High Point System - Real Data

High Point Average System - Real Data – 2008 NOTE: In 2008 the Straight Average System was used.. Same results

High Point Average System - Real Data – 2008 NO THROWOUTS

Low Point System - Real Data – Throw-outs

High Point System - Real Data

High Point Average System - Real Data – 2010

Decision Point Which System to use? Low High High Average How many throw-outs? 25% Rounded down (1 for 4) 20% Rounded down (1 for 5) 1 for the season None How many races to Qualify?
