Anybody else doing this stuff?

Even distribution along any type of belt.

Just trying to keep sushi viable for as long as possible, to be honest, but I love this kind of stuff.

Combinators on the left calculate the pacing given the belt type and a set of science types. I select one named logistical group for the set of sciences, to make manually switching a bit easier. I could do something of an automatic switcher by measuring the returning packs, perhaps. The entire belt is flushed at the top, with priority.

Any interesting suggestions, I'd love to hear.
