Hello, sorry, but try as I do I have difficulty with the rating calculaltion here. I am in a dead draw game with a player rated 1765 at table 236. I wonder if you would not mind giving me my expected loss in rating points with this draw. My rating is 2005. By way of information, I have offered twice now, but he plays on. That is ok, that is his privilage. Thank you Wayne

Rating : 2005 , 1400 = (only result) will give a rating of 1969...

Of course it depends on the other results calculated, we couldn't say it means exactly a 36 points loss in all cases. (I think)

Hmm... What about a rating simulator...

TER (Tournament Entry Rating) is used for rating calculation, not current rating !

Ahhhhhh. I just dont understand this I guess, I am confused, my TER at start of tourny was also 1400. This does not make sense to me. Guess the only way I am gonna find out is for this guy to draw. In that vain I will force a playing draw, if the 50 rule does not do it for me. Thank you Wayne

Hello Mikhail.

Looks quite normal :

You won a rated game in FICGS__GO__TOURNAMENT_DAN__000001 against a player rated (TER) 1600 and you lost a rated game in FICGS__GO__TOURNAMENT__000008 against a player rated 1900... The rating average of your opponents is inferior to your initial rating (1800).

Hello Thibault. It is not normal! My initial raring was 1800. Then I lost the rated game in FICGS__GO__TOURNAMENT__000008 against a player rated 1900 and my rating changed to 1780. It is normal. But then I win the rated game in FICGS__GO__TOURNAMENT_DAN__000001 against a player rated 1600 and my rating changed to 1752. It is not normal.

Thanks & sorry, you were right !

You were in a small rating difference range that provoked this strange result. Elo rating system has to be used carefully :/

I just updated the program & rules. Your rating has been corrected according to this change.

Thanks for feedback.
