how often should AA win in 6max n/l?

[mj2]

also, what is a decent amount for bb/hand with AA.
since i switched to n/l a couple of months ago, i've won way too often with AA. it makes me think i'm probably playing them too fast and not winning as much as i should. i have only lost once in the last 102 times i've had aces. even with the small sample size, that has to be way too much. the hand i lost i actually folded on. my standard open raise is 3 1/2. my standard reraise is 3x.
