Your new to the level. Think of all the people that have been playing there for a long time.
I just have a play bank roll, $80,600, and everytime I jump up to the 20/40 ring game, I feel like I am playing better, but I invaribly make a mistake (maybe not the first session or two) but it will eventually come.
And when I am buying in at $4000, that going bust brings me back down to where I need to drop to a lower level.
I don't like droping back down, but have since I am practicing at a new level, I must.
Now if I could just learn to get out when I have made 50% of my buy in, I'd be be moving my bankroll up. But, no, I want to double up.
Your playing tournaments though, so I guess you're just going to have to take your hits. Unless you could get your bankroll up by playing ring games. and then you would have more opportunities to practice at the level you want.
