OK, this is probably a stupid question. All these years I've always paid attention to the maintenance points only. I never really know what's going on with the other two numbers (the raw and refined materials). So what are the other two figures for? When I'm trying to generate more maintenance points, I always looked at the galaxy overview (or whatever the name is--the window in which you can see all the stuff you have), see if the mines and refineries are in balance, then build whichever are short, or build pairs if they're balanced. Is that all we have to do for resource management? I never really used 3PO to manage this.
