Maia Lichess 1546 has a blitz
Lichess rating of around 1546 . This engine is run with maia-1100.pb.gz net at node 1 on a gauntlet test below.
The formula to get FIDE Elo from Lichess Blitz Elo is,
Code: Select all
FIDE rating = 65 + [0.87 x Lichess Blitz Rating]
based from the
regression in 2019 .
Maia FIDE Elo = 65 + 0.87 x 1546 = 1410
Maia gauntlet bullet at TC 60s+100ms and is set at FIDE Elo 1410.

Ferdy, could you try Cheng 4.40 instead?
I think I fixed some minor problem with UCI_Elo (should play a bit weaker now, hopefully)

Looks like several engines are tuning to CCRL 1500 which is significantly stronger than 1500 FIDE . about 1890 +/- 100

You should try Cheese 2.2, I changed UCI_Elo calculation, based on a formula from one of your previous post.
It's difficult to find a formula that works with all possible ELO values.
In Cheese 2.2 there are 2 modes for UCI_Elo, in cheese.ini, UCILimitMode=0 to reduce the speed, or UCILimitMode=1 to limit searched nodes.
If someone want to play with it, the formula is :
speed = exp((elo + B) / A)
and there are 2 hidden parameters in cheese.ini :
EloNodesParamA and EloNodesParamB, by default A = 242.573714, and B = 749.87557
the same formula is used when limiting nodes.
Anything that can go wrong will go wrong.

I am not sure if regression from 2019 is reliable.
I am not sure if lichess rating X of 2019 is the same as lichess rating X of 2021.

I have added 2.2 and the result is almost the same to previous version. I have not touched the ini file.

What is your proposal to make the estimates more closer to the truth?
