Ya you should be able to do more then 1.3k pots/hour, since if your probably not even starting with (unf) pots you could probably make atleast 1k finished pots an hour.
Yup, all depends on how fast & concentrated you can be for long periods of time. I average only 1.1K of these, but I'm not that fast and not so very concentrated.
If you are working fast and efficient I have done about 1300 pots per hour. But usually the slow hours and the fast hours average out to be anywhere between 900 and 1100. Happy brewing
