Poker is one frustrating game. On the hold'em charts, you need to ask yourself if the downswings are a result of bad luck and fortune or leaks in your game. You really need to sit back, analyze and be honest with yourself. Otherwise, there is no improving.
I moved up to 100NL in May, so some variance and much leak plugging were expected. I'll just have to reload at 50NL on Stars and make a run at it again.
BTW - I sent Ribbo on Stox a vid of me playing PLO50, we'll see how I fair there. He said that he's gonna publish it w/ his commentary. Wish me luck.
