At the Sun and Foxwoods I always got about 30 hands per hour. This is over the course of several thousand hours of play. They both have card shuffling machines, so if you're in some backwoods place where the dealer shuffles then yeah it'll be lower.
The rake was $1 on the flop, $1 @ $20 pot, $1 @ $30 pot, $1 @ $40 and capped at the $4. Most any hand getting to the flop would hit the $40. Standard raise was $10, even one caller makes $20 on the flop and a half pot bet and call there makes $40. Let's say 80% of hands get to the flop and half of those make $40 (this is low imo, it was much closer to 1/10 hands taking it down preflop).
That'd be:
20% * $0 = $0
.5(.80) $2 = $0.80
.5(.80) $4 = $1.60
This would give a per hand rake of $2.40 (again I feel this figure is higher, but erring on the low side)
$2.40 * 30 hands per hour = $72/hour
At Foxwoods prior to the Sun's room opening $200nl was $5/30minutes. That's way easier to calculate.
$5*9 = $45 * 2 = $90/hour
They ended up moving to a normal rake structure, granted with heavy player influence, but I'm sure they didn't make the change based on the goodness of their hearts. I would be very confident in saying they're doing at least as well as they did when charging time.
