Tymon Kolasiński's unfortunate +2 official 3x3 solve prevented him from breaking his own world record and getting the first ever official sub-5 average (and only the second ever sub-4 single). His solution is simply not what I would have come up with, I would not have chosen white cross, I would not have done all his pseudoslotting, I managed to beat his official solve time of 5.75 after memorizing and practicing the scramble.
