I'm running out of useful titles here - but I need a new topic for everything so ...

Look at hydrogen refining 1. The recipes it unlocks. Yeah they are in different buildings - I'm not sure if there may be something else going on here that I'm missing. But you can have an 80% reduction in speed for the price of just 0.45 gold plates.

Similar issues with the subsequent technologies

The thermochemical separator has very high power consumption and runs on heat; even with efficiency modules, you're not going to be running too many of those per reactor. So I guess that's the tradeoff? Higher convenience for lower per-building output and a catalyst requirement. Don't think that would make me pick the injector prior to refining 3, but people have varying tastes.

At any rate, those are all 248k recipes, buildings, and techs, so if you still have concerns about this one you should take it to that mod's discussion section.

OK no worries. I'm not fully aware of where this mod has tweaked things and where it hasn't.
