A few things come to mind:Xtrafresh wrote: ↑Wed Sep 12, 2018 10:10 pmThat is indeed the goal here, though it's starting to look like a utopia. For example, every 5th train produces two extra RCU's and two extra LDSs because of the production module math. I'm not quite ready to calculate backwards to see how much less of each resource every 35th train should take along as a resultadam_bise wrote: ↑Tue Sep 11, 2018 9:37 pmIIRC not all of the fluid math is visible in the GUI, I think there are fractions not represented on screen. If so, I don't know how you will achieve such precision, but your end goal may still be achievable.
What are you wanting to end up with? A completely empty supply train for every rocket? Given that fluids may not be absolutely predictable, you might settle for simply topping off a certain number of tanks on each train visit.
Perhaps load your excess surplus and send them into outer space along with the rocket.. lol
You could also burn off some fluids with a boiler, or use recursive blueprints to decon your pipes and tanks and completely empty them between trains.
If it were me I would experiment with priming the factory with fluids and then trying to establish a fluid equilibrium using barrels. I don't know what you intend to do with the empty barrels, if you are bringing them back, perhaps figure out how many empty barrels you should introduce into the loop. If you always have some excess fluid, I would figure out how to dispose of them.
It's situations like this where disassembling items would be handy, along with automating BPs without mods.
