Because your information is incomplete, dumbo. You intentionally left out the NPC corp tax. Previously, npc corp tax came directly out of the minerals you reprocessed which ultimately translated to the best yield possible.
Acting stupid and stating falsehoods is 1/10 trolling. Pretty sad for you that you have to act in such an obnoxious manner in order to get someone to validate your existence. Mom must be proud of you for bumping my thread so much at the cost of your respectability.
