This is my 20k/min red science factory. It uses trains, blue belts, and a sprinkling of copper requester chests to hit the 20k mark.
I originally created one perfect ratio column of red science that had 12 beacons.
I extended this until the copper on the blue belt ran out, to come up with around 19k/min red science.
I wanted to hit the 20k/min mark so I added in some requester chests for extra copper to boost the factory just a little bit.
