@cojonel: I'm not thinking only about the money. It's just that I need to know if I'm not wasting my time grinding and learning or should just play occasionally for play chips. That's what I think I should do if I'm not trying to be a winning player. I'm not talking about reaching for the stars, but it's nice to know that by doing something fun you can pay rent or something now and then.
@everyone else: I almost blew the whole 50$ from PS.com, made a deposit which I'd withdrawn from another site (earned thourgh freerolls, promotions) to FTP. I said it's worth giving it another try simply because I was winning, just tilted like an idiot and entered some 1/4 BR SnGs. I'm really having fun playing and learning poker, but let's be serious: we all like to see than graph line going up!
What volume are we talking about in terms of normal speed 9-max SnGs? And about the losing periods, the strict BRM should help not to go down more than a limit, 2 max. But losing periods can also be compensated with the some MTT final table or even win. So, that's why I asked for average: It means you can win 2000 one month and lose 1000 the other... it's still 500 in 2 months.
