CCRL 40/40 ratings were set equal to a basket of engines on SSDF list at the time (2006), that list being 40/120 on an Athlon 1200 I think back then. That was simply so that there was a recognisable reference point rather then us thinking our time control and hardware combination was equal to theirs - although we thought it could be about the same, 40/120 on Athlon 1200 vs 40/40 an Athlon 64 3800+ . Subsequently we scaled the entire list down by 100 Elo. The top ratings on our list are very high, but personally I'm thankful we don't use Ordo which would expand the spread even more than bayeselo. I don't recall at the moment how we set the scale on the blitz list.

Re: UCI_Elo 1500 engines and FIDE Elo
the answer is .. who really knows ? , but from everything I have seen, CCRL has taken a very reasonable approach ..and nobody really knows if some other way would have been better ...one artifact is that we get good scaling at the high-end, but the low-end is getting compressed (more compressed relative to human ratings) ...no rating system is perfect, that is one reason why we have so many ...every rating system I have seen , if they been around long enough , has had to make a rating adjustment of some sort ..FIDE, USCF, ICCF I think even SSDF has made rating adjustments if my memory serves me correctly ...Modern Times wrote: ↑Tue Apr 27, 2021 3:37 amCCRL 40/40 ratings were set equal to a basket of engines on SSDF list at the time (2006), that list being 40/120 on an Athlon 1200 I think back then.

Re: UCI_Elo 1500 engines and FIDE Elo
The reference engine maia1 that I use is run on Lc0 node=1 limit, the same setting is used in Lichess, so this is easy to reproduce. However the ranking may change if I will change the TC from 60s+50ms bullet to TC 180s+1s for example depends on the engines' weakening algorithm. Have not tested it though.lkaufman wrote: ↑Tue Apr 27, 2021 3:22 amBased on some games I ran with the ELO 1500 to 1700 range of SF13 vs "Irina 0.15" (CCRL blitz 1436), I calculate that you would subtract 224 elo from the nominal SF ELO to estimate its CCRL blitz rating. So if I am interpreting everything properly, and based on your indications that the SF elo 1500 level would indeed be a close match playing lichess blitz with humans rated about 1500 (1507) on the FIDE scale, this would indicate that a CCRL engine with a blitz rating of 1276 would be an even match playing blitz with a human rated FIDE 1500 (or 1507). So "Irina 0.15" should be a fair match in blitz for a human rated 1660 FIDE (or perhaps a bit less as the FIDE scale is more compact than CCRL).

Re: UCI_Elo 1500 engines and FIDE Elo
OK, so this is at least a partial explanation; presumably the crippled SF 1500 would play better with more time (even an engine with bad eval like the crippled SF should improve with time), so if the Lichess games were typically played with something like quadruple the total time (for 60 moves), it would be likely that SF "1500" might get a rating there more like 1650 or 1700. So "Irina 0.15" might be more like an even match for a FIDE 1800 or a bit higher in blitz based on your data. This is at least within the realm of the plausible to me, although I would guess that a FIDE rating of 1900 to 2000 would be needed for this. I wonder what the typical time limit is for these Lichess games; although humans prefer fast blitz like 3' no inc. with each other, they may choose relatively long time limits/increments when playing engines. But I don't play on Lichess so I have to ask others to comment on this.Ferdy wrote: ↑Wed Apr 28, 2021 5:35 amThe reference engine maia1 that I use is run on Lc0 node=1 limit, the same setting is used in Lichess, so this is easy to reproduce.

Exactly, it‘s fixed to nodes=1. But doesn’t this mean it plays independently of time control? The only difference can be how humans perform on different time controls against the exact same opponent.

Re: UCI_Elo 1500 engines and FIDE Elo
Yes there is no time control in maia1's setting, it is replaced by node control, the idea is that it can play on different hardware and get the same strength every time, the time element is erased. Human strength can vary due to time but perhaps not much at this Elo 1500 level.KLc wrote: ↑Wed Apr 28, 2021 8:49 amExactly, it‘s fixed to nodes=1.

Based from regression,
FIDE Std. Elo = 65 + 0.87 x Lichess Blitz Rating
Lichess Blitz Rating = (FIDE Std. Elo - 65) / 0.87
FIDE Std. Elo = 1500
Lichess Blitz Rating = (1500 - 65) / 0.87 = 1650
We can extract data from people with Lichess blitz rating of around 1650, then get its rapid rating, do regression and see how close these people can get with added time that is from blitz to rapid.

Re: UCI_Elo 1500 engines and FIDE Elo
On my computer (i5 2500k) when I run 100 games at 60s+100ms with Cheese 2.2 vs Deuterium 2.37.73, both at UCI_Elo = 1500, Deuterium is +188 ELO better than Cheese.
Am I doing something wrong ?
Anything that can go wrong will go wrong.
