I see you have raised this via the feedback form Neill, so I would appreciate you also posting the follow up on that when you receive it...

Entirely to be expected as the system for juniors has weighted the balance between lag and randomness much more in the direction of randomness.
To amplify this, all grades are potentially wrong so if you get results which don't agree with the previous published grades, do you
(a) presume the results to be random fluctuations and make a small change to the previous grade
(b) presume the previous grade to be incorrect and make a large change to the previous grade.

There are other measures of deflation, but on the face of it based rapid play grading list, there is evidence that people playing rapid play are getting weaker.

Does anyone know? I know it is probably a stupid example but what is the answer anyone ?
Brian Valentine wrote:Roger,
I agree the process is unstable, especially when juniors may even be in the majority (depending on the influence of entrants and leavers. However I think Neill is pointing out another issue in that more players (that are measured) are declined than those who have grading increases. This is consistent with those playing most games being those who have rising grades.
This situation may or may not represent the reality. But it doesn't do much to enthuse the next generation of chessplayers.
