AI Advantage is a game global variable - it will be used at the point troops are bought at whatever you have it currently set to. It is not "locked" to your campaign. (Campaign difficulty level is locked to your LC, but that reltatesz to how many buy points you get awarded for your victory level after a game ends).

So feel free to change it if needed, provided you do so before any AI troop buy, the new value will stick.
