I've been trying this as well. I started with a 3.50 fr cash, nearly bust it, cashed in the 25c like you, more cashes and got it up to about $12 then all the way the back down to my last $. Cashed again in the 25c and now back up to $5. That's been about a month of play on Stars and it's been a real slog.
But enough about me . In answer to your question, obviously standard BR practice goes out the window when you are so shortly rolled as we are, but you can still get a lot of play out of it. I would recommend playing with a 10x rule. So stick to the 10c games until you have 2.50 or more then switch to the 25c tourneys until you can get up to $5, then to the 50c until you can get to $10. Once you can get past 10$ you can start looking at what else you might want to try, but don't let yourself get dragged back down to pennies again like I did because I started the $1 and $2 games, missed, and its a real bitch to have to start all over.
