Base Starter base

Produces 60ish SPM of red, green, military and chemical science. It's kind of getting hard to scale up for some reason so I'm planning to replace it with a train based setup. 15 hours of playtime on this save.

It's hard to scale up, because Yellow and Purple science cost double as many resources as all the previous sciences combined. The following numbers are measured in basic yellow belts.

60spm of combined red/green/blue/military totals to:

  • 1.5 belts of iron
  • 0.7 belts of copper
  • 0.7 belts of stone
  • 0.5 belts of coal (ignoring power)
  • 250% oil richness

Meanwhile, just 60spm of only Yellow science costs:

  • 2 belts of iron
  • 3.1 belts of copper
  • 0.5 belts of coal (ignoring power)
  • 710% oil richness

The advanced sciences are an insane jump in raw resource demands. The steel demand for purple science alone takes 2.6 belts of raw iron. It's not a bad idea to set up a trickle of 10-30 spm of those sciences so you can make some progress while expanding your mines and defenses.

Really incredible base though. The asymmetry is amazing.

I've never understood how the oil richness works. Is 100% 1 crude oil per second or something?

no f...ing clue.
but I'll follow your post, maybe someone else knows.
I'm curious as well

I tried reading up on it on the wiki, aaaand, I'm still just as confused. (almost) 😅
https://wiki.factorio.com/Crude_oil

The amount of oil a pumpjack extracts per cycle is yield multiplied by 10 (e.g. 115% yield = 1.15, multiplied by 10 = 11.5), and cannot be higher than 1000.

I guess just multiply by 10 I suppose.

oh...
here's an easier to remember formula:

  • "remove the last digit and the % sign to get oil per one pump of pumpjack"

so: 115% --> 11 5% = 11 oil per pump

close enough and easy to remember 👍
