I did not believe my results of Stockfish 13 and the next development version Stockfish Dev. 200221 in the 50 player tournament at 1s+1s. I have never seen that big of jump in Elo performance.

Code:: 2 Stockfish 200221 avx2 373 38 449 360 5 84 402.0 89.5% 18.7%
3 Stockfish 13 358 36 448 351 4 93 397.5 88.7% 20.8%

But the 5m + 5s results are confirming that results.

I guess the Fat Fritz 2 release really pissed them off.
