Mumble, Purge, all:
Well I stand corrected. Seems I was wrong, just my play style was such that I wasn't noticing. I re-ran the test, and took very copious notes, and built no morale buildings that might screw with my results. Here is what I saw:
Tax rate 19% always. Overall morale = what shows up in your stats and graphs tab as a racial modifier.
Overall morale - 65%
21b pop = 29% approval (-70 pop, -20 tax, +1 buildings, +18 native)
16b pop = 67% approval (-48 pop, - 20 tax, +2 buildings, +33 native)
11b pop = 100% approval (-28 pop, -20 tax, +3 buildings, +46 native)
Overall morale - 80%
21b pop = 33% approval (-70 pop, -20 tax, +1 buildings, +23 native)
16b pop = 75% approval (-48 pop, - 20 tax, +2 buildings, +41 native)
11b pop = 100% approval (-28 pop, -20 tax, +3 buildings, +57 native)
Overall morale - 85%
21b pop = 34% approval (-70 pop, -20 tax, +1 buildings, +24 native)
16b pop = 77% approval (-48 pop, - 20 tax, +2 buildings, +43 native)
11b pop = 100% approval (-28 pop, -20 tax, +3 buildings, +60 native)
Overall morale - 100%
21b pop = 39% approval (-70 pop, -20 tax, +1 buildings, +29 native)
16b pop = 85% approval (-48 pop, - 20 tax, +2 buildings, +51 native)
11b pop = 100% approval (-28 pop, -20 tax, +3 buildings, +71 native)
Overall morale - 105%
21b pop = 40% approval (-70 pop, -20 tax, +1 buildings, +30 native)
16b pop = 87% approval (-48 pop, - 20 tax, +2 buildings, +54 native)
11b pop = 100% approval (-28 pop, -20 tax, +3 buildings, +74 native)
Overall morale - 206%
21b pop = 80% approval (-70 pop, -20 tax, +1 buildings, +59 native)
16b pop = 100% approval (-48 pop, - 20 tax, +2 buildings, +100 native)
11b pop = 100% approval (-28 pop, -20 tax, +3 buildings, +100 native)
So it seems that yes, if you are going to have planets with very high populations, then very high morale bonuses DO matter. The only other difference I can think is I ran this test on cakewalk, and my previous test (and all my games) on suicidal... doesn't make sense there would be a difference though.
I obviously play with low enough populations and enough morale buildings that I just ceased to notice the slight increase vs. the steep decrease you get from increasing tax rate. Again, I apologize for leading anyone astray... It seems really your empire bonus will max depending on max pop size on one world.
Hope this information can also help anyone in deconstructing the formula overall. If you stick to populations in the 15-16b range, with two VR centers and all worlds terraformed so getting the natural +10, you can sit at 100% approval at a 79% tax rate, which is close to what I normally play with.
Of course, now I'm off to start a game with the Krynn trying to make those giant 40b pop worlds....
