Lichess blitz rating - FIDE ELO - DWZ comparison

@ Rawkward

Thank you! :) :) Its my pleasure!

Thanks for sharing the ChessGoals website @Ledator-Youtube

I'll try to monitor this thread for questions, but I admit I'm not very active on the forums :-)

Happy to answer any questions, and there is an explanation video on the rating comparison page.

One further argument for the statistic of ChessGoals fitting better/being more accurate is, that ChessGoals only accepted data of players, who played enough games recently on lichess blitz and FIDE ELO rated over the board. So maybe we should tend more to this statistic....

@Nh31-O from the link I posted there are linear regression paremeters
[1] "rapid"
Coefficients:
(Intercept) x
309.9946 0.7962
so rough 310 + 0.8 * 2000 for you = woudl make somewhere around 2100 but please do not that at best accuracyis +-200 points. also you see this from scattergram that lichess 2000 falls between 1500 and 2500 with 90% probability. i.e all estimates are worthless.

@ smarterchess

Youre welcome! :) You are the author of ChessGoals, right? Thank you for youre awesome work! :)

Yes, that's my website :)

Nevertheless, Elo, USCF and DWZ say little at the moment. This is because OTB tournaments have not been played for a long time. Because of Covid. That's why Elo, USCF and DWZ show the level of performance that you had before Covid and not your current performance.

That is also the reason why tournaments in Germany are only evaluated within six months after they have ended.

@ odoaker2015

Yes, exactly!

@odoaker2015 is this some covid-19 thing or during normal operation also?
