The math of doing ten shows is interesting. Theoretically, five, then a meal break, then five more, with fifteen minutes in between, and you're taping for exactly eight hours. Now of course you'd need staff there in advance, and you'd need some time to shut things down when you're done, plus there would inevitably be SOME delays as you go. Still, if you treated it as a product you were churning out, it's not as though it would take a herculean effort to do ten in a day.
