So here's a question for a system build -
Looking to set up a local(ish) refinery as by now even the closest Trailblazer support ship is some 90-ish light years away and will only get further - while being the closest sub-100ly supply station for anything (and also running out of ceramic composites, steel and titanium plus a few other things, but that's another subject) - and bugs of economy transfer notwithstanding, my plan was to set up four refinery hubs and a Coriolis in orbit, plus possibly a T3 planetary. Is four of the hubs going to be enough or should I build a fifth one as well?
There is six slots available on that planet anyway, and I haven't decided if it would serve better for a T1 planetary (I don't plan on building two T3 planetaries and I don't think this system has enough slots to make that work with my plan anyway*, as the solitary moon of planet 4 is reserved for some industrial sites I've already got planned out) or that fifth hub. If we had more refinery option buildings I'd just put one of those down instead. But as is... I'd like to know the better option.
*Nor would I want to build two tier 3 planetary stations, the system is not big enough to be worth that effort, nevermind that I'm not acting as part of a group in this.
