What exactly are you trying to beat? In poker, you don't need to constantly win in order do well and make a profit. In fact, it's possible to win every hand you play or every tournament you enter, so it's best to get out of that mindset that you need to in order to be successful.
It's been years since I've played MTTs online and I just back into because of the covid-19 shelter in place. I play microstakes ($1-$3) and I've played 91 MTTs so far. My ITM is 16.5%, which means I've only cashed in ~15/91 MTTs. I even went on a 31 and 17 game downswing since I've started playing. However, even given my large downswings or the fact that I busted out of 86 MTTs without cashing, my RO1 is 95.56%, and I have a profit of $155.35.
So, am I beating
online poker? It depends on what the goal is. My goal is to profit off of it and I'm down that. I don't need to win every hand or cash in every MTT to do so because, again, it's impossible. If you think you need to win every hand you play in order to be successful, you're just setting yourself up for disappointment. Just keep making those +ev decision, run well, and that's all you can do and that's really takes. Get your money in good and, in the long run, it'll show.
Also, talking about my stats wasn't a brag and I apologize if it came off as such. It was just to get a point across. I used to be where you were when I started playing and I had the same mindset you did, so I understand where you're coming from.
Best of luck to you.
