The ROR I play to is <10% (usually right around 9%), depending on the game and location. I resize pretty much constantly: I look at CVCX's numbers before every trip and find the optimal bets with a <10% ROR.
When I first started, I played with a 10% RoR. As the BR grew, my risk tolerance has decreased; it is now at 1%, and I am currently considering bringing it down a little bit more due to some more recent growth.
Hey those are my chips! My bankroll so big I cant keep it in the bank. To stay diversified I've spread my bankroll around all the casinos. Before I get there they always put a a few thousand on each table so i can verify they still have it - at least in chip form. They "lend" the money out to locals at horrible rates so when i come back I always have more than before.
