"Most of your profit will come from AA & KK"

[phydaux]

That is a quote from a friend of mine, a pro player who plays 400NL on several sites.

I had said in a differant on-line poker forum (yes, there are OTHER on-line poker forums) that, with normal size stacks, 50% of a FR NL players profit will come from AA & KK. The other 50% will come from set farming.

My friend the pro said, "No, most of your profit comes from AA & KK. Set farming makes up, at most, 40%."

I was wondering what you guys had to say on this. Or rather, what your stats had to say. Does AA & KK really make up such a large fraction of non-short stack's total profit?
