@rRigbyCoal Thanks man! With -%60 upgrade the value should be 0.08 as this is the %40 of 0.2, also if you have the engineer skill that improves reactor fuel efficiency, I think the effect is multiplicative with the ship upgrade that improves the fuel efficiency. So if you have like -40 efficiency from upgrade and -20 from the skill, the total in this example would be -52, not -60.

Hi, I really love this sub and I appreciate all of the hard work you put into it, but I have a (possibly dumb) question about calculating the fuel efficiency of the reactor. The default you put into the memory component is 0.2, so when I get max fuel efficiency upgrades (-60%) and the terminal tells me to divide it by the percentage, would it be 0.125? Or 0.5?
