We can get that scaling with very simple logic and formula.

1) The cont benefit goes to the empire that has the most territory on that continent.

2) The size of the benefit is the fraction of territory * the benefit.


So if a continent's max benefit is 20% training bonus to aircraft and there's a 3-way fight going on the continent with even distribution, the empire that squeezes ahead and gets 34+% would get about a 7% training bonus for owning the continent during that 3-way battle, and they could get more by gaining more territory up to a maximum of 20% for owning the entire continent.

So you'd get value for every single territory up until the entire continent is captured.

That's a good way to scale it naturally and provide continual rewards for further domination and to value even the wilderness territories.
