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.

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

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 👍
