I have just checked some info by alexman on the AA interception rates at Apolyton...
I have varied the experience of the units and this does effect the interception rates as does varying the Aircraft interception rates (from the default of 50%). This agrees with testing done by somateria at http://forums.civfanatics.com/showt...100#post1498100
This is similar to the real world, in that you do not want your flaks shooting in an area with your planes... When I raised the interception to 100% only 2 bombers out of 100 were hit by flak as opposed to 21/300 without... (Regular v. Regular, Bomber D = 4, AA Defense = 4)
More testing is definately necessary, I have verified that 'Preserve random seed' is off for each test...
So far my formula is (Preliminary Formula):
The four best AA units are used in the calculation...
(1 - [AirUnitsDefense/{(SumofAAUnitsDefenseInTile*0.10)+AirUnitsDefense}] * UnknownFormulaForExperience * (UnknownFormulaForInterceptionRates--maybe?)
Note: alexman's formula gives very similar results to mine, minus my unknowns...
I base the above on a preview of some of the data below:
Bomber D = 4, AA D = 4, Both Reg, Int @ 50% --- 21/300 (7%)
Bomber D = 4, AA D = 4, Reg B/Vet AA, Int @ 50% --- 27/300 (9%)
Bomber D = 4, AA D = 4, Reg B/Vet AA, Int @ 50% --- 31/300 (10.3%)
Bomber D = 4, AA D = 4, Both Reg, Int @ 100% --- 2/100 (2%)
...I have much more data I will post when I am finished
To support the cumulative Defense assertion:
Ratio of 1:2 (BomberD:AAUnitD)
Bomber D = 2/ AA D = 4, Both Reg, Int @ 50% --- 58/300 (19.3%)
Bomber D = 4/ AA D = 4x2AAUnits, Both Reg, Int @ 50% --- 53/300 (17.6%)
Ratio of 1:4 (BomberD:AAUnitD)
Bomber D = 1/ AA D = 4, Both Reg, Int @ 50% --- 90/300 (30%)
Bomber D = 2/ AA D = 4x2AAUnits, Both Reg, Int @ 50% --- 87/300 (29%)
Either way, we are on the right track, but maybe someone from Firaxis could give us the exact formula...
