F-category ratings are ratings which don't qualify as A-E category and which, in 'normal' times, require 1+ results in the previous 12 months and 5+ results in the previous 36 months. In my view they're statistically meaningless and ought to be discounted.Roger de Coverly wrote: ↑Mon Feb 14, 2022 7:03 pmIt's a 219 F though, based on just six games, four from Northumberland and two from the 4NCL.

That seems fine doesn't it? He has and ECF 2343* rating in February 2022 which is a conversion from his ECF 219 grade in July 2020.

If you ignore F or * grades, what alternative do you have to determine seeding or section?Angus French wrote: ↑Mon Feb 14, 2022 9:13 pmF-category ratings are ratings which don't qualify as A-E category and which, in 'normal' times, require 1+ results in the previous 12 months and 5+ results in the previous 36 months.

You could use International Elo (FIDE ratinhgs) or National Elo (Scottish & Welsh for example).

Re: Doncaster Congress 25-27/2/22
I digressed a bit, but per example I have entrants with a * temp grade, no fide, no national grade. It's still my best guess, better than online ratings: someone who drew 3 games against 1900 might not be 1900, but is a reasonable approximation of his 1600-2200 strength. I wouldn't play him with 1400s.Roger de Coverly wrote: ↑Wed Feb 16, 2022 4:09 pmWadih Khoury wrote: ↑Wed Feb 16, 2022 4:05 pm

The organiser can reserve the right to use "organiser's estimate" for those without a published OTB ECF rating where "published OTB ECF" doesn't include * or F ratings.Wadih Khoury wrote: ↑Wed Feb 16, 2022 4:12 pmI digressed a bit, but per example I have entrants with a * temp grade, no fide, no national grade.

Re: Doncaster Congress 25-27/2/22
An updated entry list will soon be available via Steve Mann's website.
Regarding ratings:
-A player's January Original rating has been used to decide section eligibility
-A player's February Revised rating (at 1900, 18/2/22) has been used to decide tournament grading
Where a player does not have a current ECF rating the most appropriate alternative rating has been used
