Mean Winning Hand in HE?

I mean average (mean) winning hand in HE overall.

In Draw, statistically, most hands (some 60%) are won by 2 pr. The mean hand, counting higher hands such as flushes, is 999. In other words, if you aren't trying to make better than 999, you are behind the drawing field.

So... what is the most winning hand in HE -- is it 2 pr? What is the average (mean) winning hand? Anyone know?

I read that it was two pair, but my database shows that for me it is somewhere between one pair - top pair and one pair - second pair. That is, at showdown, those hands win just a little more than 50% of the time. Obviously any hand can win if it doesn't go to showdown.
