I'm curious to know how it's all calculated. If you're using a flat calc to determine the "average" inventory of most players I propose this is not the best way to determine current needs. I have several 4* crafter friends whose inventories are empty. If their inventories are empty or nearly so then my assumption would be that there would be others too. If this is the case then would it be possible to use a different system in order to maximize storage across all players and move storage slots around so as to expand overall storage? The end game player would never see any of this "movement" but could the servers adjust in order to maximize all slots across all players?
