I have been intrigued with this concept since I read a couple weeks ago (yes, it's old news):

Per Meni Rosenfeld:
"If you distribute your hashrate among multiple pools in proportion to their respective total hashrate, your variance will be as if you mine in one pool with the total hashrate of all pools."

I wonder, since my math is crap...
1)  does this apply equally to all payout methods?  PPS, PPLNS, DGM, Slush, etc?  Or is the concept applicable to a specific payout method only?
2) does anyone have results or comments to present based on Meni Rosenfeld's proof?
3) what have other miners done to leverage this or similar concepts?  Such as "I use x many pools, of what pool hash to my hash power ratio, using cgminer --load-balance, etc, resulted in less variance."

Anyone?  Bueller? Gracias!
