This contrasts with Elo type systems that can have a longer built in memory.<br /><br />In response to AWIC, the ECF grading system is one of the oldest in the world, dating back to the 1950s. If we retain it, it is because the increasingly elderly English chess public, many of whom have been playing since the 1960s or 1970s are familiar with it and its foibles. The International system is plainly struggling with all the improving players that it let in by reducing its floor to 1000, so it isn't just a question of flicking a switch to use Elo methods for national ratings without working out how to handle Juniors and others showing rapid improvement.<br /><br />RdCAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-37675897.post-66474454195603438442014-03-13T23:38:36.887+00:002014-03-13T23:38:36.887+00:00Sorry - maybe I'm not making myself clear.

I reckon (based on some fag-packet calculations) that there's about a 1% of this happening by chance - so unlikely but not totally impossible (if 10 bloggers played 10 games a year for 10 years, you'd expect one to end up over-rated by 15 points or more at some point). <br /><br />If it was based on a sample of 30 games, it would be much less plausible to have happened by chance, and much more likely to be indicative of a problem with the system.Matt Fletcherhttps://www.blogger.com/profile/13885091955173203114noreply@blogger.comtag:blogger.com,1999:blog-37675897.post-71960016614813775442014-03-12T19:32:49.961+00:002014-03-12T19:32:49.961+00:00Ashish, English club games are played on weekday e...Ashish, English club games are played on weekday evenings and so typically can't be rated because the time control is not long enoughJonathan Bhttps://www.blogger.com/profile/00293162543015231439noreply@blogger.comtag:blogger.com,1999:blog-37675897.post-72259335933648445462014-03-12T18:36:27.864+00:002014-03-12T18:36:27.864+00:00Why don't the English teach their children how...Why don't the English teach their children how to ... rate games by Elo?

Average players and the average grade used to be in the 105 to 120 range. This was boosted to 130 to 145 with greater increases lower down and lesser ones higher up. As one might expect, this is having an effect of feeding upwards. A shortage of ambitious eighteen year olds taking points off established players contributes. Those of IM standard have observed that whilst their International ratings remain in the same range, their English grades are increasing. They've also commented that some of the 200 graded players they face regularly are not of that standard.<br /><br /><br />RdCAnonymousnoreply@blogger.com
