THX!!!

@ zero, I am trying to keep my laptop windows office free ;-)

looking the numbers:

if I got the system, to score 1000 you should win at least 15 races indipendent of the time frame, right?
found my new goal for the next years! lol

I found a mistake in the previous spreadsheet, so I've attached a corrected version. You can get 1000 by winning 10 of your first 15 races. Otherwise, you need to gradually increase your rating by winning. Depends on your starting rating for how long that takes.

Maybe we should We are thinking of including a decrease in the rating, which would make it difficult to stay at 1000, let alone get there.

Hi Scotsman - getting closer! I ran a few of the recent long races with the latest set of numbers and the results are credible. There is a definite bias toward slower boats, but I'm not sure if this is reflecting the method of handicapping or the nature of long races.

A very interesting summary to look at is corrected time vs handicap for any given race. Ideally you'd end up a with a flat "limit" with cruisers etc scattered above that. For leg 3 there is a positive slope. Interestingly, you can also see the 24 gaps that boats were able to transit the strait in - within each group the trend holds true. Good news for the system.

I'll start processing results on the basis of my previous posts.

Hmmm, any chance of sending the results for the recent races like you did before? We have those up to #448 25 Feb 2012.

Any thoughts on how to host the results or the data? We can continue with this thread for now but at some stage the results should go somewhere more obvious.

I've analysed the ratings for the race #449. See attached. This spreadsheet includes updated rating and corrected results.

New SOLers can have very low ratings as they have not completed many races. This seems to skew the results. We may need to give them a higher starting rating which is more realistic until they have completed a few races.

Here are the next two race results. Whilst this is working ok, could do with some programming advice on how to improve it. Bit clumsy at the moment.

Joanne's Test Race Zone

In 1947, Hugh McLean & Sons of Gourock, Scotland built a radical racing yacht for John Illingworth, soon-to-be Commodore of the RORC, to a design by Laurent Giles. With a masthead rig, giving her ‘free’ sail area per the rules of the time, and short overhangs reducing pitching, Myth of Malham went on to win The Fastnet that year and again in 1949, and to compete in numerous Admiral's Cups. In 1958, in honour of the yacht, the Myth of Malham race was conceived - a mini-Fastnet to the first lighthouse on a rock west of Cowes, Eddystone, rather than the second, to be held in non-Fastnet years. IRL this year it has been raced already, but this stops us not from “Red Eye” racing its online 230nm in Fareast 31Rs, leaving how to deal with the Isle of Wight open to your own discretion.

We invite you to another race, which will kick off the third quarter of our ARCH series.

Nantucket Sprint 2025


Welcome to Nantucket, from whence Herman Melville’s Cap’n Ahab sailed round The Horn into the northern Pacific Ocean to hunt the gray whale - whose migrations are celebrated elsewhere in SOL’s Q4 schedule - he never to return. And whaling too, as the 19th C progressed, like Ahab disappeared from Nantucket as the harbour silted up and mainland Massachusetts whaling stations benefited from rail connections. But beach life, yachting and nostalgia has rescued the island from oblivion, so to celebrate leisure, SOL gives you the Nantucket Sprint - 25nm in 29er_XX’s from east of Tuckernuck Island across the sound to a finish just inside the mouth of the harbour. Enjoy!

Aland Sea TIMED Race
Norrtalje Segelsallskap, 70km NE of Stockholm was founded in 1920, and time was when the society’s season opened with a challenging offshore race from the club line off Flaten island at the mouth of the long and narrow Norrtaljeviken, out onto a triangular course around the Aland Sea, to finish at Simpnas slightly to the north on Bjorko island - some 78nm in total. A fine race that SOL, being from these parts, ran annually up until 2013. Last run in autumn 2018, we return here to race the course again in the form a TIMED RUN in spanking new Club Swan 50s.
