That "100%" analysis is very deeply flawed. The author of the video even issued a retraction (https://twitter.com/IglesiasYosha/status/1574308784566067201...).

It's cherry-picked games and it doesn't compare to the "engine correlation" of other high ranked players against similar opponents. I would not rely on it as evidence that Hans is "clearly cheating."
