No, I don't use anything like that. Just (obviously) Poker Tracker, and stack the tables.
I spent a bit of time yesterday and today going through my financial situation. Looking at all the bills I'll need to pay, and estimating my income for the rest of the month. There's a chance I won't need to withdraw at all this month, but if I do, I might only need to cash out $100 or $200.
What I'm thinking about doing is sticking at nl2 until my next paycheque (in about a week). And then depositing what I need to bring my bankroll to $500. This would give me a bankroll of 100BI for nl5. Then I can comfortably (and professionally) grind nl5 as my "base level". Obviously, I would need to then cash that amount out, plus any additional money I might need, by the end of the month. But most likely, playing at nl5, I'll have made more than enough to cover that. Especially if I put in 200k hands the rest of the month (so variance is not a huge risk).
I already know I'm a winning player at nl5 (if I just go back to basics, and none of that GTO-type experimenting stuff). And by 22 (or even 24)-tabling at nl5, I'll be able to make enough side income to pay the remainder of my monthly bills, and continue to grow the bankroll. Or build up a bit of a financial cushion first.
The experimenting phase is over for now, but might start doing that again in the future once I'm playing a bit higher. I almost feel like I should start a new thread, as the title is misleading now lol. Except the first part, I'm still trying to go from nl2 to the top.
