Packaging machine speed is easy to calculate. Just count products out, divide by time, and you have instantaneous speed per minute. In theory, you should be able to multiply by 480 to get output per shift. In reality, that instantaneous speed probably doesn't match shift output. During the shift, the machine may have stopped. That may be because the operators went to lunch, because the upstream or downstream machine stopped, because it had its own problems, or a host of other reasons. What you are really interested in is output: how many pallets can you get on the truck at the end of the day? This is related to speed, but is not the same thing.
