Correct, complete formula for resource production:

(base facility production rate) * (planet's resource value) * [(empire's racial characteristic modifier) + (empire's cultural modifier) + (planet's happiness modifier) + (population modifier)] * (Resource Gen Modifier Planet modifer) * (Resource Gen Modifier System modifier) = resource production

No Phongs were harmed in the derivation of this formula. Plenty of Jraenar were, however.

Note that the ability "Resource Gen Modifier Planet" is the ability used by Mineral Scanners, Robotoids, etc. The ability "Resource Gen Modifier System" is used by System Mineral Scanners, System Robotoid Factories, etc.
