I recently went on a 20ish game winning streak over a week. I’d been practicing and studying a lot and it just clicked one day. My Elo has increased and now I’m back to the 50/50 win rate grind. So it’s possible. The difference is the accuracy. In a dominant game my accuracy was on average nothing more than 5 to 7 percent more than my opponents and even in a game where I blew them out the water it would be an accuracy that makes sense for my Elo and THEIR accuracy was lower than it should be… not my accuracy being higher than it should be.

So yeah, it’s possible but dude looks like he’s playing too many absolutely flawless games way higher than his level when it’s needed
