Strange Game Analysis Behavior

This is a bit strange.

I played two games of 2-1 bullet on LiChess. I copied two of those games and had Chess.com analyze each one. The rating under Highlights was 1950 and 2050. When I play 2-1 bullet on Chess.com and have it analyze the games I never get above 1600! A few weeks ago I did the same copied paste analyze with the same ~2000 result!

I don't get it. Any ideas why this is happening? I certainly don't play at a different level on each server.

The ratings estimate is based on the ratings of the players and the resulting accuracies. Your rating on Lichess is likely higher than here so it should get expected a game from there will have higher estimates than one played here.

If you take a game and change the player's ratings, the rating estimates will be different if you run a review on that as well.

I copied 3 of my games on LiChess, stripped the ratings and names out and only had the moves, then copied to Chess.com analysis board. In the Highlights section of the analysis my rating based only on each game is 1600, 2200, 2300.

Now, my Lichess rating is around 1400 for that time control while my Chess.com rating is around 900. How is it possible that Chess.com analysis engine is saying my games are at such high levels when it's obvious I'm a patzer?

I have a similar problem i have no idea why 15..Qd7 is a mistake
