Hi there,
I'd give it a few months to see if your gains continue or at least you don't drop but in any case, this looks like a good sign!
By the way, I am rated over 2400 online (https://www.chess.com/member/ppandachess). I created a free course that will teach you a training plan to improve. Feel free to check it out: https://www.panda-chess.com/daily-improvement-plan
I recently made it my goal to reach 2000 elo (I'm 1260 now) and in attempts to gain rating I've only been playing anywhere from 1 to 5 games a day and gaining about 7 to 20 elo a day. I'm proud of how far I've come in just a month or so but my main concern is if I'm actually getting better at the game. Should I be playing more or am I fine how I am now?
