variance for 6 max nl?

[jordiepop]

Ive never really heard this discussed before. Ive been playing 50 nl for awhile, going up and down up and down. for the past two days ive won 11 buy ins, and today i just dropped 3 all on ridiculous stuff. I know nl has lower variance than other forms of poker, im just curious what kind of swings you guys have gone through. And whats normal?
