I looked through the forums but I am confused.

I'm playing micro/small full ring NL at poker. (for example, $25NL, the lowest they have for normal players).

I've read that a good hourly win rate is 1BB/100, possibly even 2 BB/100. Is this TOTAL hourly win rate on multiple tables, or what?

lets say i play 3000 hands in one day at 0.10/0.25 NL (multitabling of course). If my BB/100 is 1 BB/100, that means I make 0.50 * 1/100 * 3000 = $15 in one day.

Is this the correct calculation? So basically by playing a LOT of hands, all I can make at $25NL is $15 a day?!?!?

THis does not make sense. Furthermore, in 100 hands, that means my expected profit per hand is 0.50 / 100, or $0.005 per hand?
