Thanks again people.
Is there any way to see my population growth rate at DL? I can't seem to find it anywhere.
edit: Also, any tips on how the sliders (miliatary, social, etc) work? I can't seem to pin down why my bc go up or down when I move some sliders.
Population growth in DL is a value of between 3 to 7% (Torians are the only 7%) up to a maximum of a base growth of 75M population/turn, before bonuses (which are shown under Civilization Manager-->Stats & Graphs:Abilities). Unfortunately, there's nowhere in the game that this value is actually shown, but 4% is a safe estimate.
In DA/TA, the 75M maximum base is calculated with growth factored in, which means that if you have say 1250M pop with a 4% racial growth factor and a 50% pop growth bonus (Aphrodisiac, for instance) that gives you a 50 base times the 1.5 = 75 base (maximum base) times 1.5 pop growth bonus (again) = 112 (the .5 is truncated) actual base growth, times approval bonus. But this extra term doesn't apply to DL; in DL it would only be 50 base growth times 1.5 racial bonus = 75 base pop per turn times approval bonuses.
Hope that made sense.
The sliders have been explained as employment, but that doesn't make a great deal of sense, either. In any case, in order to build improvements, build ships, or research, you must have the appropriate infrastructure: factories, factories, or labs. But your total infrastructure funding must add up to 100%, which means you can't run all three (or even two) of them at 100% capacity simultaneously.
How much you pay is equal to total funding * individual funding * infrastructure capacity (counted on a planetary basis) * (1 + racial bonuses / 100) * (1 + building bonuses / 100). Research is summed at the end of this, but industry is on a per-planet basis. Oh, and as with almost everything in GC2, the final result is truncated (rounded down to the nearest 1).
Side note: In the above equation, bonuses from techs, anomalies, customization points, inherent abilities, political parties, both planetary and civ-wide events, mining starbases, and economic starbases, are all considered racial bonuses; they stack, rather than multiply.
Additionally, in TA 2.x, the Technological Capital no longer increases actual research output by 100% (doubling effect assuming no other research-modifier buildings are present) for the planet, but instead is counted as a racial bonus, which means that due to the hidden research bonus on higher difficulties than Tough, at a certain point that is achieved relatively early, you'll actually have less research output as compared to the same setup in DA.
I've forgotten how asteroid mines factor in, though. Apologies for that.
And, in the above equation, you pay for all of the (funded) base production of a given type, but only half of the (funded) bonus production-the other half is free.
Finally, there's the focus mechanic, which allows you to transfer (funded) base production only to another production type, losing 25% of your (funded) base production of type A and transferring it to type B at an efficiency of 100% (DL/DA) or 80% (TA)-and after it is transferred to type B, it gets type B's bonus, not type A's.
Let me know if that wasn't clear enough, or if you were asking questions that I didn't answer.
One last thing: The Artificial Slave Center, which increases your military production by 50% via a multiplier (that is, *1.5, not +base*1.5) interacts in strange ways with how military costs are calculated, so if you have it built and you see numbers that don't match the above, then that's why.
