I don't see a reason why a long race should be weighted differently from a short race
Thank you. This was a mistake by me. One of the intetions was to value longer races more, since it's more likely that the race order will reflect the ranking order. But if a stronger skipper beat a weaker skipper on a long course, it should give less points than on a short course, since the probability to win is higher on a long course. But if a weaker skipper beat a stronger skipper on a long course, it should ideally give more points than a victory on a short course. Therefore this length parameter has to be included in the probability to win function. I will look into that. The other intetion of this factor was to give more points for longer races since it's takes more time than shorter. Instead of playing only short games to progress fast in the rating, this would stimulate to also play longer races. But I must admit this isn't very relevant as soon as you rating has stabalized at your skill level.
So if you want Harald, i can send you the code, database etc.
to play around with. Only needs to be ported to ASP and or Msql i think is what the vsk servers run on.
Jean-Pierre (Sothis) is actually working on a huge database with course records, tournaments and rankings. He will implement this rating formula there. He will very soon open for beta tests for ITBYC members.
