Note on Stacking
A lot of numbers that Alpha Centauri uses are modified. In some cases, modifiers stack arithmetically and not geometrically. For example, if there are two +25% modifiers modifying a base number, that base number receives and overall +50% and not a +56.25% (two separate increases of 25%) modifier. In most cases, however, they stack geometrically.
Examples
-If a base has both a Network Node and a Fusion Lab and is producing 8 labs base, it will produce 16 labs total (+50% from the Node and +50% from the Lab for +100% total, not +125%.) (However, if it also has the Supercollider, it will produce 32 labs and not just 24; project-based increases to energy stack geometrically.)
Modifier stacking follows the following rules (please add anything not included):
-Energy production percentage bonuses from facilities stack arithmetically. Project-based boosts (Supercollider, Theory of Everything, Longevity Vaccine, Space Elevator) stack geometrically. -Mineral production percentage bonuses stack arithmetically; this includes the +50% mineral production from the Bulk Matter Transmitter. -Combat modifiers stack geometrically, but "scaling" combat modifiers such as that for morale, or for PLANET rating in psi combat, scale arithmetically.
