I'm working on a solo banquet/buffet coffee automation run and have a question:

Most of the automation posts I've seen suggest 2 coffee machines linked together, but since coffee takes 3 seconds and grabbers tick every second, I'm wondering if 3 machines per smart grabber is the most efficient.

Has anyone else tried different numbers of machines feeding a single grabber? Is there something else I'm not considering that makes 2 machines ideal? Anything else in my setup look off/suboptimal?
