Is there any way to measure, on a per starbase level, the economic benefit one is derving from them? Say I ramp up an economic starbase as far as I can and it sits across various trade routes (not just mine) - how can I determine how much that particular starbase is contributing to my income? In other words, I'd like to put a value on each base so as to see how strongly I should be defending them.
