well, I can't say it's not true. But it does at his purpose I guess. in the mid game (early space) I found my patch running out really fast on nauvis (two outpost to rebuild everytime I came back from setting up a new planet) and once I step up my core mining (two blue belts) the problem was way less present. Plus it gives you access to a trickle of pyroflux before you go to a vulcanite planet
