Performance rating calculation

so recently,  20 days ago I participated in a tournament where I got a 28.5/29 score against players of these ratings, but I can't find a way to calculate the performance rating, please help. 1228, 1579, 1086, 962, 2032, 1317, 883, 1361, 1450, 792, 2179, 1745, 813, 1661, 1027, 1256, 1028, 1190, 1810, 647, 669, 1480, 1363, 1885, 631, 1553, 700, 1440, 1748, in chess

I tried to ask chatgpt but it told me 850, how does a 850 rated beat so much good players

Which one did you lose to?

Draw with I mean.

I double-checked on another site and the same result came out. On the link above you'll find some explanations to understand the difference between performance rating and FIDE performance rating.

woah thank you bro

I was going to estimate it about 2400, so not too far off.

Based on the TPRs I've gotten at arenas and other tournaments.

I drew with FM Sherlock Holmes rated 2000 here

Whoa very nice.

So yeah, very high TPR. 2400 or so using the way variants calculates it, around 2350 if you don't count strength of opponents that you lost/drew against.

thank you jack

if I didn't count the draw then my performance rating would be infinity
