How much are you pumping?

I'm EBF but pumping to get a supply for when I go back to work, and I'm wondering if I'm producing significantly less than I should. For those of you who are pumping, how many ounces are you getting per breast per pumping session? And what kind of pumping schedule do you have? When's the best time to pump?
