Aces Cracked Promo: Value per hour?

[carddown]

Two local card rooms offer "Aces Cracked" promotions, and one of them is expanding their offer to several days a week. One place rewards $100 and the other pays $60 for Aces Cracked. Surely, there is a formula to determine the estimated value per hour of this promotion, but I'm unable to find it. The promo is for any game, but realistically, we're talking here about a 3/6 limit Hold 'Em game. I guess you can use the results for any game if you figure out a value of the promotion independent of your pot investment.

Another statistics question: I know how often I'm likely to get pocket Aces, but how often am I supposed to be playing against them at a full table? Is it still 1 in 221, or is it number of players/221?
