That is number of pages of players below 1000 RHP rating vs 5 pages of over 2000 RHP rating. Yes, I have no moves to make, resisting the urge to add a bunch of games. Patience keeps the gameload manageable...
Originally posted by ExumaFirst see how hard it is to get to 2000, and then find out how hard it is to get to 1000. Now do you see why?

Originally posted by ExumaStill, I think his point is that the list does not follow a non-standard normal distribution. It would be interesting for someone to plot the frequency distribution to see what it actually looks like. Like the poster, I just asumed the distribution followed a normal curve.

Originally posted by petrovitchJust because there are more people under 1000 than there are above 2000 doesn't imply that the distribution is not normal...

Of course, if you think about it the curve couldn't be normal since everyone s ...[text shortened]... res.
This is all guess work. We can only tell if someone will go to the trouble to plot it.
Originally posted by monteirofYes, but your rating can drop a long way in 100 days...
Rankings updated every hour.
Provisionally rated players are excluded from the rating table.
Provisional ratings (< 20 rated games complete) prefixed by a 'p'.
Non-movers in the last 100 days are not ranked.

For example, if the distribution was normal with mean 1300 we would expect there to be more people under 1000 than above 2000...
But, yes, I think you are correct in sayin that the distribution here is probably not normal due ...[text shortened]... that provisional and non-provisional ratings are calculated would probably have an effect too.

You know you can play Blitz while waiting.

To Petrovitch - thanks for the work you put in - that is a really interesting project - I too was under the impression that the number of high ranked (over 2000) players would be unnaturally high - especially given the amount of computer accusation that goes on. ...[text shortened]... es for a player to reach 2000 here, ignoring actual time.

Originally posted by petrovitchI stated there was no correlation between a player's rating and the number of games played. I guess I'd better back that up with evidence. Remember, these figures are real-time so while the mean, standard deviation, etc. should remain very close they may vary from one examination to another. So this mean may be slightly different from previous means examined in other threads. It changes with every game played on this site.
That question can be answered in three parts.
First, the number of games played is not correlated very highly with ratings. This is because many weak players play thousands of games an never improve their game. The don't play to improve; they play for fun.
Second, a player who is serious about his game will continue to impove throughout his/he ...[text shortened]... games, but study, to get there.
Third, players already of that strength, about 300 games.
