"loose" play and variance

[pete fabrizio]

I don't quite understand your question. Why work on my game if I'm already winning? Ask all the Party 15-30 "pros" who have seen their bankrolls evaporate.

That thread you linked to is unmanageable, are there any highlights?

Generally, I don't think the BR issue is that interesting, since it's pretty much solved. In PLO the variance is about 100BB/hr, so a bankroll of 3000BB is basically sufficient even for a player who wins 10BB/hr. And it's pretty easy to calculate your risk of ruin given winrate, standard deviation, and BR -- in my poker spreadsheet, I just have a risk of ruin calculator.
