Relative game size?

[cryptical]

I was talking with a friend a bit ago, and we were trying to figure out the relative size of a 2-5 blind NL game, and a 5-5, no max buy-in on either game. I think the 2-5 would be around 10-20 limit size, and the 5-5 might be like a 15-30. Anyone have any ideas? Thanks.

In my experiance, it really depends on how much money people have behind them. The longer the game goes on, the bigger it gets. I'd say a 5-5 NL game seems like a 15-30 game though just because I like to sit down with minimum $600 on each.

are you referring to size in terms of attainable winrate, or the bankroll you gotta have to play?
