I agree with shadroch. That is one of the reasons full tables are so deadly to EV. Most people assume 100 hands per hour, so by playing at full tables you are cutting your profits in half.
On the other hand, I've seen lightning-fast dealers who could easily deal 200+ hands per hour without breaking a sweat or missing a payout. Playing at a good online casino can get you even more hands than that!
