Rating results for Akl Tga.

--- Last Edited by NZL Scotsman at 2012-04-10 01:02:30 ---
A thought on the handicap results: The top places are usually taken by SOLers who have completed very few races. One way to avoid this would be to use their best result as their rating until they have completed 15 races. Another way would be to increase their rating by a particular % based on number of races completed.

The rating becomes easier to handle after the initial 15 races are complete. This is function of how we are establishing the initial rating. Using fewer races would speed up this process, but risks having less valid initial rating.
Well... getting an initial Ranking is always difficult because of the fact that it's initial. ;)
I think no one would take an initial Value that serious to complain about it. Maybe one can mark it as initial or not confident in the Ranking.

I don't know the formula for getting an initial Ranking. If i would be asked how to get one that's converging relatively fast to a "real" value, i would suggest to take the arithmetical Medium of his ratings so far, until he's sailed a certain amount of races, say fifteen.

If that's too difficult to do, i would reduce the minimum number of Races to be sailed for an initial ranking, but introducing a Mechanism to lower this ranking afterward, if necessary.
I didnt actually notice the last few posts until after I had done this, but I tapped directly into the DB to output lot more data you could use (going back to Jan 1 2010)

2 files included:
* boats_data.csv - full race-id;race-name;boat-name;ranking;elapsed time;ET components (D;H;M;S) - approx 3.8Mb
This file is sorted by race start-time, and then each boat is in rank order within that race.
* races_data.csv - is data for all the races referenced in boats_data.csv - race-id, name & extra info like #started, #finished, race start time, polar used, Series etc...

56,845 data rows in the boats_data file - that will fill up ya spreadsheet!!

Note: the data is SEMI-COLON separated, as in the race data file 2 fields are themselves comma separated lists - so make sure to remember this when importing into Excel or whatever...

Also Note: The DB seems to have a few 'inconsistencies' in it, 2 or 3 races didn't record finish time (atleast, not in the way I grabbed it for other races?) and the like, SO - these are not included for consistency/completeness

Download zipped data here (914Kb)

HTH :-)

Also, if you provide me with specific formulae you are using, I could script it up and run it over the DB similarly to what I did here - then ideally integrate it into the ranking system

Please note - it is only because I have a 'non-racing' account on SOL with admin privileges that I could do this...
(And know just enough to write Python scripts to pull info out of the DB)

A preliminary attempt to make these results public can be seen here

It will grow and evolve in display sophistication over time...

Bookmark it - perhaps later it will be added to the Links page or something (looking into better alternatives)

Sailonline’s 15th Birthday Balloon Race
Sailonline offers a huge variety of boats to sail in. One of the more unusual ones has got to be SOL's Balloon, which was polarized by past SOLmaster 76Trombones. Notably, the SOL Balloon will actually ‘sail’ in other directions other than straight downwind, although it will not 'sail' over land or beyond a 'beam reach'. Like in 2013 and 2018, we will be taking the Balloon across the Atlantic from St. John's and 'land' it in the sea off the Cliffs of Moher.
