MrWCF: How did you come to that conclusion? You said the player in question had played four games against people whose ratings were 1341, 1094, "unrated" and "unrated". How do you know that those "unrated" ratings were actually not very high ratings? I mean even if you have an "unrated" rating, it is expressed in numbers in the BK system. For example, you have finished, to date, 2 Embassy Chess games. After a quick look at your profile, however, I can tell that your BKR is somewhere between 2298 and 2445, yet it is shown as "unrated".

I know (or at least strongly surmise) that the unrated ratings were not high because the two games against unrated players were actually against the same player who happens to have a Cam record of one win and two losses.  That cannot possibly be a high provisional rating I would hope, right?  That fact, coupled with the ratings of the other two opponents, allowed me to question the 2100 provisional rating. 

Moreover, I don't really care about the 2100 rating, in itself; I am far more interested in how it was calculated.  I still don't have an answer to that question.

 

MrWCF: I've just found out that Jannssen's BKR was at 2100 already after the very first game he played. That was against Hrqls, who had played only 1 Cam game before that (he won against Robsaranga).

Pedro Martínez:Wow!!!
