There are 5 efficiency modifiers in the bonus list... Fuel Eff, Supply Eff, Research Eff, Planet Develop Eff, and Upgrade Eff. The normal bonus multiplier for other items are straight forward eg. Supply Production bonus mux of x1.3 would yield 130% normal supply production. This is not the case for efficiency mods. These mods effect cost calculations such that an efficiency mod of 25% or x1.25 results in a 20% realized reduction in cost. The cost is calculated by... Actual cost=base cost x (effec mod^-1) -or- Actual cost=base cost x (1/effec mod)
Working example:
Fuel Eff = 1.3
Normal Fuel units needed = 400
Actual cost = 400 x (1/1.3) = 307.69 Units
Note that 307.69 x 1.3 = 400 so you can see the modifier is described accurately.
The term 'efficiency' was chosen for lack of a better term.
