Question: Tournament Performance Ratings (Lichess)

I played a couple of the Lichess tournaments last week, 2 of them but only played a single game in each, I won both of those games and after downloading the results .csv files I was shocked to see my performance at:

tournament 1: (886 out of 1547 players)
886,, SYN-RG, 1184, 2, 2033,

tournament 2: (388 out of 720 players)
388,, SYN-RG, 1193, 2, 2047,

Was my performance in both of those games really over 2000? I am not even rated 1200 Rapid!

Performance is somehow calculated using win rate, the opponent against whom you won or lost. It doesn't go on rating

performance is based on your "opponent rating and result of games" average
loss= -500 than opponent rating
draw= opponent rating
win= +500 opponent rating
performance= average of all these values
as far as i know

@MoralHelper

That seems to make sense, I beat a player rated 1500+ (who bezerked) and then I won by resignation, so technically it could be deemed a 2000+ rated performance in context, but was merely a result of how Lichess calculates said metric.

Thanks @MoralHelper and also @Akarsh_2010 for your input
