It totally doesn't matter if I make redstone dust worth 20 atoms instead of 16 right? Also turns out I was being an idiot and this is way easier then I thought. For a different question, is there any way to add dummy items? Ones that aren't obtainable in any way but I can still use for my recipes? Because that would actually let me have carbon as a result of decomposing steel which it's not currently, still have to overcharge for synthesis though due to GT actually having a realisticish amount of carbon in it and minechem not liking that unless you like synthesising your steel dusts a stack at a time.
