Eeek, am I doomed?

[Possum]

No doubt the answer to this is somewhere within the hugely long "Tips & Tricks" thread, but...

The question concerns defensive to-hit modifiers in SEIV V1.94/v1.95

ECM III 60%
Stealth Armor III 15%
Scattering Armor III 15%

Do all three of those stack, for a total defensive to-hit bonus of 90%?

****edit****

Testing in the simulator seems to suggest that they do all three stack.

I use two Light Cruisers (CL).

CL Alpha
Sensors III
ECM III
PPB's

CL Zulu
Sensors III
ECM III
PPB's
Scattering Armor III
Stealth Armor III
Emissive Armor III

I fire up the Simulator, turn off Computer Control for Race 2, assign one cruiser to each side.

Hitting begin, I drive both cruisers to the middle of the map, and park them 2 squares apart.

Alpha's chance to hit Zulu is 43%

Zulu's chance to hit Alpha is 77%

Now, the difference is 34%. Clearly 30% is from the Scattering and Stealth armors.

Given that both races show "Average" for Aggressiveness and Defensiveness, where does the other 4% come from?
