You can still ask Skuzzy 
Most games have a simpler goal for gameplay. In a car racing game it's easy to determine ranks. But AH is a giant sandbox. With countless different approaches to gameplay.
But I am very curious if you have any suggestions for a meaningful score system.
Ok I think in the abscence of an understandable approach the add all the squad overall scores together and divide by ther number of squaddies is the best I can come up with. Minimum number of squaddies to qualify should be 12 as squad means for me at least this number.
As far as the detail is concerned make landing as in not dying more important in all categories to give realism for those who want it. The more Arcade orientated propbaly wouldnt mind as score is long term recurring.
It should be easy to remove some of the idiosincracies like the single rocket atack on buildings and make the gv score lean a bit more toward K/D survival. In other words dongrade the ground pounding except in bombers of course where that is the raison-detre anyway.
(Appologies I couldnt get the spell chck to work)
