How big is a batch?

I have read so many pieces about this bakery or that where they say this oven makes so many batches over a certain period or this bakery holds the record for consecutive batches...

So, having not been trained by a school or a professional baker, how big is a batch? Is it 2, 10, 20 or what? For me 10 loaves in a row at 2 pounds each was a great workout kneading but the time really flies when you are having that much fun!

Happy baking!
