Greatest match/tourney ELO performance ever?

I see Markus Ragger of Austria has put in an ELO performance of 3379 so far in the 2017 Tata Steel event. That's like playing at Komodo level?

That seems pretty bloody amazing. But what's the best ELO performance of all time in a tournament or match? (So not a single game)

I know lots of patriots are now going to chime in and say RJF's two 6-0 wins in the Candidates. But is that actually the case?

Wikipedia's chess records doesn't seem to have anything specifically for performance ratings but it says Wesley So won the gold medal in men's blitz at the SEA Games 2011 at Indonesia with a score of 9/9 and a rating performance of 3183. That seems to be the highest one mentioned. Anyone up for updating that wiki with a highest performance rating entry for Markus Ragger?

Thanks. Could you perhaps provide a link to the page you mentioned?

True performance rating is impossible to calculate if you win every game.  For example, I once went 5/5 in an event against class C players.  However, a 2000 could probably do that.  So could a 2200, and a 2400, and a 2600, etc.  You can't know the maximum achievement of a player in an event if they always win, because there's no ceiling.

I believe Caruana at Sinquefield is the highest and Magnus's at Nanjing is right up there as well.

Let's hope he draws one somewhere down the line and his perf can be measured.

@regicidal - thanks!

alex: his record is 4/4 with opponent average rating about 2550.  He's only gained 13 ELO points

I doubt he'll maintain it.  He's the highest rated player and has already played the second highest rated (Xiong).  I think he's also the oldest player, so he'll probably take a few quick draws if he's ahead in the event.  Even a few draws against 2500 rated players would drop his PR back to still-impressive but not superhuman levels

I believe that Fischer held the record for highest rating performance with 3000 in the 1963 US Championship, but Karpov might have played objectively stronger chess to make 2977 at Linares 1994

Karpov 1994 was a beast

Caruana in the 2014 Sinquefield Cup. He won 7 matches in a row, then played 3 draws and got 8,5/10 in one of the strongest tournaments in chess history. His rating performance was at an astonishing 3102!

Caruana's 2014 Singuefield and Karpov's 1994 Linares are amongst the very highest, Fischer's 6-0 over Larsen in the 1971 candidates is the highest match elo performance ever at 3080 I think.
