I just got this game the other day, and most of the time since I've been trying to figure out the enigma of allocated spending, more specifically why it sometimes fluctuates as you move the distribution sliders around. For the sake of simplicity, assume in the following that industrial capacity is always set to 100%:
What I have figured out is this: When techonology spending is set to 100% of the budget, the allocated spending (minus bonuses and maintenance) is based entirely on your techonology capacity. When military or social spending is set to 100% of your budget, the allocated spending (again, minus bonuses and maintenance) is based on your manufacturing capacity, and whether or not you are actually manufacturing anything.
The question,then, is: what is it based on when you are using some mix of budget allocations? This I have not figured out. It appears to be some kind of complicated formula based on a weighted average. One thing that is certain is that your total allocatd spending, minus bonuses and maintentence, can never exceed either your technology capacity or manufacturing capacity, whichever is highest. This I find to be extremely unintuitive. It seems to me that if you have the spare capacity...why can't you use it?
Maybe someone understands this better than I do who can help me. I like to have a full understanding of these sort of games before I really get into them so I can play it well. The whole spending aspect of this game, to me, just seems incredibly over-engineered, as if there were too many cooks in the kitchen during the design phase of the game. I dunno, though, maybe I'm just missing something obvious...
I guess I should also add that I am using v1.4x of the game, for what that's worth...
