Based on the formula in th
Newbie FAQ:
(Extraction Facility value) x (planet�s resource type %) x (empire�s racial %) x (Planet Robotoid Facility %) x (System Robotoid Facility %) x (planet�s happiness %) x (population %) = total mineral resources committed to your empire for that facility.
Construction rate is as follows:
(rate of SY facility OR 2000 if no SY is present) x (empire�s racial %) x (population %) = total build rate
Note that a modifier of 10% means you multiply by 1.1.
Note also that racial % is the sum of Construction Aptitude, advanced racial traits (Hardy Industirialists) and cultural modifier.
