What is your hourly win rate in a?

I've heard of 1-2-5 but never a 2-3-5 game, sounds neat. I imagine it plays about the same as 2/5 NL, whose buy-in is usually 100 to 500 (but at some places 200 to 1000). You won't be rich playing it, but you can make a living from it, if that's why you ask. Even $1/2 NL is enough to make a living from. If I had to guess the different between the two games, I'd say you can make 2/3 the profit at $1/2 as you can at $2/5 (the players in $1/2 are fishier, that's why it's more than half). I guess since I'm anonymous I wouldn't mind telling you my rate if you're truly curious. But it would have to be in several weeks because I only recently began logging my sessions. So if you still care then, I'll PM you.

Also, I'm only referring to live 2/5; online might be a different story because you can multi-table. Or even at a single table online you get probably twice as many hands per hour (live is about 30 if the table has a shuffling machine), or more if it's a shorthanded game like 6-max.

I'm going to assume you mean live, because I've never heard of such a blind structure online. Well, it is assumed a 10bb/100 winrate is sustainable. You may be getting 25 hands/hour live. That would come to 2.5bb/hr. The thing is, live games are much juicier than online. Something like 3.5bb/hr may be attainable for the best in that game. At $5 as the bb, that would come to $17.50/hr. More or less depending on the rake structure and possible rakeback deals for high volume players. This is up to many difference factors, such as the number of regulars, the toughness of the game generally, and the possibility or impossibility of game selection (is there only 1 table going normally or many to choose from?).

That's not a structure available at any online site i play. And I play at lower limits anyway.

It doesn't matter what my win rate is. It matters what yours is. Most people who are profitable in the long run can consistently (barring vairance) make 2BB/100 hands.
