Add the : Metal Ratio, formula : (metal income / metal outcome) x 100 This value shows relatively how much you spend regarding how much you gain. 50% means you lose twice what you gain 100% means you lose as much as you gain 200% means you lose half what you gain Energy Ratio, formula : (energy income / energy outcome) x 100 50% means you lose twice what you gain 100% means you lose as much as you gain 200% means you lose half what you gain Economic Efficiency, It is the fabrication rate of your factories and fabricators. It is the lowest value of the two previous ratio (metal and energy). Except that the Economic Efficiency can not exceed 100%, and as long you have ressources in your stock, this value won't go under 100%. 100% means that your factories and your fabricators produce at the maximum of their capacity. 50% means that your factories and your fabricators produce at the 50% of their capacity. Colour code Blue = you are wasting ressources (it is bad) green = good yellow = you are on the edge orange = you lack ressources red = clearly stop building stuff !
