Now, in only 100 games gauntlets against Zurichess Bern (2232 Elo CCRL) and BikJump v2.01 (2098 Elo CCRL), it performs at about 2200 Elo level at 1s/move and at about 2300 Elo level at 10s/move. On a full 4 core i7 CPU.

On my own testing I've got slightly lower results than that. I've been matching it against old dedicated machines from the 1990s and giving LCZ ID 83 an Nvidia 1060 card to run on and >100,000 rollouts per move (Game in 30).

Although it is impressive how it outplays the weaker dedicated machines, especially with exchange sacs for positional compensation, it often gets hit by their tactics.
