[sailwave] Re: Progressive / Personal Handicap

So now that Jon has released the beta version I’ll share some of my comments I’ve made to Jon while testing this over the last week.

  1. the plugin works well and doesn’t appear to have any bugs errors. I’ve used Byron handicaps as baseline.
  2. I’m not totally convinced by the system as it is in effect a personal handicap creator! Where a couple of one designs would normally be adjusted together to give a single h’cap, they are now given a boat specific correction. I for one would like a means of selecting OD boats so that a single correction is applied to those boats.
  3. I have been scoring using Byron and an alternative based on PYS which has 5yrs of data loaded in. The differences between all three are only subtle, and perhaps strengthen the credibility of Byron as a basic measurement system, but also show that within reason the PYS site now being used for returns is adequate for producing club cruiser handicaps.
  4. I only though of this today, but the RYA NCH system creates an IRC type number, tending towards a tie up with IRC in order to try and determine if IRC is actually maintaining a fair formula.

So it seems to work but I wonder if it’s just another choice to muddy the waters at smaller cruiser clubs.

I am the Handicapper at Flushing Sailing Club and a long time user of Sailwave. Together with all of the Cruiser racing clubs in Cornwall we have been in discussion with Bas at the RYA and waiting for the NHC to be released for testing, which Bas has said is this weekend. A key part of it is the Sailwave plugin. I would be delighted to participate in testing and have plenty of Cruiser results.

Hi William,

That is what this NHC does although initially designed for cruisers.

There

are two models one for Club racing and one for Regattas. You would

be

looking at a Club racing model. This NHC works by having a Base

rating

which is set by the RYA and lets say we have a boat that competes in

the

Wednesday night series and a Sunday Series.

After each race their handicap gets adjusted based on performance of

the

race. The series are separate so their Wednesday night handicap

will

be

different from their Sunday handicap as the conditions are typically

different for evening racing. At the end of the series a carried

forward

handicap is calculated which they will use if they compete in the

next

Wednesday evening series and another carried forward is calculated

and

used

for the next Sunday series.

Thanks for the heads-up, Jon, but I guess we will only find out what

adjustment algorithms are used after the dinghy show announcement?

FWIW my views on race-by-race adjustment are written here

http://groups.yahoo.com/group/sailwave/message/9311> , but as I need

to

hand over the Lancing SC handicapping job so someone else, I’m

interested to see the RYA’s approach.

Cheers
