It all depends. Some weeks I'm very productive and some weeks things go slowly. At the beginning of my session before a firing, I may make a handful of pots a day. Closer to the firing deadline, I'm filling up tables, checking off my make list. Ironically, when I'm at the top of my throwing game (like now!) it's time to stop making! I should have stopped making pots last week, but my make list says that I still need so many of "x, y, and z". The compounded effect of this deadline kind of thinking is that the last minute making steals from the time I need to paint and glaze the existing pots and then steal again when they, too, want to be decorated. The image in my mind to describe this is one you might be familiar with. You know when there is an traffic jam on the interstate and everybody politely is waiting, then somebody decides that they are more important than the rest and passes in the breakdown lane to get to the front? That's what the pots that I made yesterday will be doing to get into the kiln by Friday.
So to answer your question (or not) it varies. I try to average about 20 pots of various sizes a day. I also try to balance pots that require trimming and post-wheel work with pots that just have to be turned over to dry.
I'm not very good at making pots and decorating at the same time, so I tend to "stockpile" my bisque ware and sit down for a week before the loading and firing of the kiln surrounded by stacks of plates, jars cups, etc. All of them waiting for some sort of decorative treatment. Once I get rolling the intimidation of that many pots melts away and the exhilaration of painting patterns becomes exciting.
So, Brett, I hope that approximates a good answer to your question.
Here are a few pots I've made in the last couple of days.
