That's true, I'm 2050-2100 lichess, around 1800 on chess.com. Never played a rated tournament but played some rated players who were 1400-1500 rated USCF, and they were roughly my strength, maybe a bit better. Still the Delta bot, easy mode, was much, much better than me.

I heard it's never intended to be the same since initial rating for Lichess and chess.com respectively is 1500 and 1200. So they should have 300 rating difference on average. Quite fitting with what the other commenter claims actually.

It's still significantly stronger than the average online chess player
