So I was wondering if, while digging through the game's code, you've ever run across the exact formula Halo Wars uses to determine Combat Efficiency and Bonus Multiplier in the Post Game Carnage Report. I've never seen an exact explanation, the best anyone can seemingly do is say it's based on kill/death ratio of units and buildings, and possibly even the cost of the those units in Supplies.

It'd be great to have the actual formula in order to see whether seeking out high cost buildings and units is really more beneficial, or if it's based on population kill/death. This would be helpful in learning exactly what kind of strategy is most best for upping the multipliers and get that "Running The Show" achievement faster. :)
