I think alot is player style dependant. See the tables below:
This is over my last 58k hands. As you can see, the dealing distribution looks pretty normal. I was dealt AA less than any other PP, but otherwise it looks pretty normal.
My style is more to see flops with 22-TT, and I am much more likely to 3-bet or raise a bunch of limpers with JJ-AA, so you see that number of flops seen greatly decreases as we reach JJ+
