I really like this mod, it can fill a perfect niche in between the basic forge and the industrial one if the speed is set just right. I'm having issues tweaking that to feel 'just right' though. The description of the math ('Refines Metal 10 times faster x2') was troublesome to figure out.

What I've found is that the SetCraftingSpeed=7 effectively translates into 10x whatever the number is.

IE at speed=7, that's 70x normal rate for a single forge, and speed=1 is still 10x. So I ended up setting mine at 0.5, which means that 2 gas forges are cranking out bars at more than double the rate of the bank of 4 forges we previously were using. With only a bit of gasoline as the needed fuel.
