Variance in Equity over Large Samples

[Murd0c]

I was wondering what type of variance in expected equity could be expected between a large group of people, say 1 million, over a large sample size of hands of NLHE, say 1 million hands. What kind of % difference would there be of expected equity between the "Luckiest" person and the "Unluckiest" person?

<.1%? 1%? 10%?
