About 20%, but it was nearer 33% when I first moved up to this limit.
I'm taking some huge up & downswings (max $850, min $400), but so long as I keep playing my sensible game it's building up slowly. I'm aware it's risky, but my entire $600 bankroll has come off a $60 deposit, so I'm happy enough to risk it and I've told myself I'll drop down a limit if it goes below $300.
Right now I'm just trying to keep a level head and cut my variance down. I've caught myself tilting twice, but been able to build things back up afterwards.
I'd never move up beyond the .50/1 tables playing like this, but for now I feel the small bankroll is helping me learn the hard way that poker's a game of control, and that slow & steady is the way to go.
My long term plan is: If I can hit $1500 I'm gonna cash out $1000 and buy a new fridge freezer. If I can build the $500 back to $1500 after that I'll move up to the $1/2 tables. If I actually am playing well and it's not just luck hopefully I'll have the fridge freezer early next year, with the $1/2 tables following sometime in the summer.
