How good is 2100 on lichess?

If you trawl through the forum posts, somebody posted a link to a website which estimated your rating based on a few tactic puzzles. I can't remember if it was FIDE or not though....

Here you go,

I got 2100 in bullet. I'm 1545 FIDE. Hmm.

I had first rank in chess. I played equally with one person, who was almost a CM. So, I think, you could get candidate master category, if you would participate in OTB tournaments.

I'm about 2100 on here, FIDE 2077. At least from my experience, lichess ratings quite accurately represent FIDE ratings.

I do know, however, of many people who are 2100 on here but much lower IRL, so I'm not sure.

I'm 1947 FIDE in rapid (10min+5sec). Been half a year since I played last time, so I can possibly be a bit better now, but unlikely higher than 2000.
That site mentioned in #3 though gives about 100 points higher estimation (judging by the comments) and is rather for measuring blitz strength.

I got 1752 on that site. Maybe I just suck at playing on internet.

I'm 2000 on lichess and unrated FIDE. So its really inaccurate.

@9 something is inaccurate :)

If you really want to know your fide rating ... take part in fide tournaments... The number itself is only ever a guidline to relative strength amongst a group of (x) players over a certain time control.
