When does BB/hr become a good measure?

When you sit down to a Cash game playing NL you had better make sure you come with a good bankroll !! I'm not talking Tournaments now, where you ppay a small entry and vie for a Big Payout. The analogy of Micro limit Hold'em games pales in comparison.

I suggest a little reading will go a long way. Dollar winrates don't mean much when a maniac goes all-in and u call him with AA and he flops 2 pair. And You called with 10000 chips.
