Ever since I picked up chess, it didn't take much for my playing strength to increase. All I had to do was play some games, watch some YouTube, and wait for a set amount of time... and then whoosh! I'm suddenly stronger by 100 elo points. I never even knew what it was that got better in my game ─ I just started beating opponents I struggled with previously and that's it. The improvement just... happened. And it still does! The only thing that changed from my beginner days is the amount of time that it takes for my rating to jump by 100 points ─ it used to take only a few days, then a week, then a couple of weeks, and now it takes about 1-2 months. But the process is exactly the same ─ I don't need to do much to get better.
I think you're humblebragging.
I guess I should have scrolled down a little farther in your game archive 😉 10 minutes is a good time control but people have been saying 2200 in rapid is where it starts to get hard so we'll see if your improvement slows down.
True, I've noticed that some of the 2200s and 2300s are really strong. But that won't stop me from beating them in the near future, hopefully
