Using an ultra-high ELO chess engine to score each possible move, then reversing through the players moves and seeing how often it would have been a positive move (one that shifts the balance of the game in your favor) - or perfect move (not sure which). It is extremely rare to make 100% perfect moves in a game, let alone a series of games. Typical gameplay for high level chess player doesn't peak over 72-75% for a given series of N games. Niemann has several tournaments over this and several games with 100% perfect moves. The inconsistency is also a concern since he goes from mid-60's to 78/79 in a span of one tournament.

His games against Magnus were exceedingly high.

It's also worth pointing out that a player's odds of making the perfect move are inverse to their opponent's ELO: as the level of play rises, finding the right play becomes exponentially harder. The data suggests he's sometimes playing other grandmasters as good as those grandmasters would play a rando on Lichess.

It's Elo, not an acronym.

It's not extremely rare. Stop pulling things out of your butt.

THE FIRST GAME Hikaru opened when he tried to check his games was 100%. He opened a random fucking game!

GP is not pulling this out of their butt, they are summarizing the video like GGP requested.

Also, your anecdote doesn't prove anything.

If someone wins the powerball the first time they buy a ticket it’s still a rare event.

yeah - if I pulled a random willing powerball ticket out of my massive pile of powerball tickets, that would be a really, really rare event. It would make me believe that it isn't such a rare thing, for sure.
