More ratings questions

This time one big chess. According to rules for big chess (I actually read it first before posting :), it says that the original rating that is used for calculations is the correspondence rating, which should have been 1785, however it appears that 0 was used instead. In the section that I almost finishing I am now 5 out 5 with 1 game left. The ratings of the other players ranged from 1800 down 1200 (roughly) initially. My current provision rating is 1609 and it seems that all my opponents have lost at least 200 ratings points in the process of playing in this tournament.

If rating system had used a real low rating as the initial for myself it would have been unfair to both myself and all of the other players in my section.

Big chess ratings

Hi Lazaro!

"Big chess ratings are first estimated from current correspondence chess ratings (current rating -300 points, with at least 1400), then adjusted in real time after each result (...)"

When you entered your first big chess tournament, the TER was not specified but your current correspondence chess rating was used (minus 300) to calculate your first big chess rating with your first result, so a rating of 1609 seems ok taking account of your opponents ratings. The first results may look quite arbitrary but some rules prevent to lose too many points when losing against a strong opponent with a low rating. Anyway there should be more class categories to get more chances to improve ratings (to be continued), we needed more players but maybe we can do it now.
