Lichess is considered to be inflated compared to chess.com due to its slightly smaller player base.
There is also the fact that players start at 1500, making that more or less the baseline. You could play against a new player on lichess who is 1500, while that would not happen on chess.com.
Is there a formula or a correlation between your lichess rating and chess.com rating?
Because I have around a ~400 point gap with Lichess being at the higher end
But I know many people who have around a ~100 point gap with lichess still being at the higher end.
I wonder if it all depends on which site you play on more?
