Whether or not grading inflation has been occurring (or occurring within certain segments of the population) I'm not really sure that your grade can be taken as evidence of it, yet alone "reliable" evidence. It just looks like the sort of statistical outlier that can sometimes occur when somebody who doesn't play much ("c" grade) has a particularly good result/set of results.Jonathan Rogers wrote:pleased with my record grade, though I cannot be delighted, knowing that it is a reliable sign of grading inflation. I was still probably more dangerous in the mid to late 1990s.
What about your FIDE rating, broadly static since 1993? I don't think there's any systemic inflation there. I know it's based on relatively few rated games, because you play in England, but still should be enough.Jonathan Rogers wrote: That is why I think that grading list inflation mainly explains my highest ever grade just now, at comfortable middle age.
At the lower levels, the relationship between ECF grade and FIDE rating is all over the place. In my pairing this afternoon in round 1 of the Major Open, I face an opponent 1 ECF point higher. Seeded pairings have been replaced by semi-random ones, as measured by ECF grade. The ECF rule that treats all juniors as new players would be inflationary where it not that it isn't actually used in the calculations for the next list.NickFaulks wrote: What about your FIDE rating, broadly static since 1993?

That is an old story and the reasons for it are well known. At Jonathan's level there is no reason why it should be the case.Roger de Coverly wrote: At the lower levels, the relationship between ECF grade and FIDE rating is all over the place.
Is your point that I haven't really declined all that much, if at all, over the years, and so suddenly getting my highest grade is not such a shock and thus not a sign of grading inflation? (I'll answer this, if so; just checking first that I understand).NickFaulks wrote:What about your FIDE rating, broadly static since 1993? I don't think there's any systemic inflation there.

Hi Anthony,Anthony Higgs wrote:There appears to be a problem with the list, I (selectively!) quote a colleague and grader as follows:
"If you check your personal page you will find you're shown as having played some number "x" games over the last 12 months. However, if you then click on "Standard games played, last 12 months" you'll find a greater number "y" are recorded. Whilst your internal club games played since January are listed, your opponent's grades are not shown for these games. These games seem to account for the difference between "x" and "y". This seems to be a common problem for many, but not all, of the clubs for which I submit results. I don't know if this has affected the grading calculations. I'm on the case with the Grading Administrator."
Yes, that is suggested by your FIDE rating history. You have gone from world #3500, in an era when the system had not yet discovered many players of that strength, to #6000 when most of them ( I suspect ) have been found.Jonathan Rogers wrote: Is your point that I haven't really declined all that much, if at all, over the years, and so suddenly getting my highest grade is not such a shock and thus not a sign of grading inflation?
