“Ah yes, but remember also, the defense bonus DOES stack, add the Stealth Armor, Scattering Armor and ECM together and you get one tough ship!”

If I understand you,
1 Stealth Armor III + 1 Scattering Armor III + ECM III
Will give you greather ECM than
2 Stealt Armor III+ 1 ECM III
or
2 Scattering Armor III + ECM III
