So my notes when I was planning min rate say something completely different than what I actually made. I guess what this does is a 20 cycle loop that makes 5 of each product using the reactive water and 3/4 of the available rusts. The other 1/4 of the rusts is used to make 1 copy of each output which get slung around into the outputs. There's a little stealy switcheroo that takes a reactive water and a rust from the main pipeline to feed the baby pipeline. Arms 18, 19, and 20 feel a little unfortunate but that's life.
