Assuming Black Out is 25 agents minimum (correct me if wrong)
[edit]OK so its 15 agents and I made a MAJOR miscalc by forgetting to double the sec centres.[/edit]


Cov Opper with Dictator = 100 + 25% = 125 base stealth.

new_stealth = (old stealth - 5 - int(No_of_agents*0.5) )
new_stealth = (125 - 5 - int( 15 * 0.5)) = 113

random(20) + new_stealth - target_alertness must be higher than 1 for the operation to succeed.
20 + 113 - alertness = 1 (1 or lower is fail, 20 is highest possible random)
alertness = 132

So you need 132 Alertness to 100% stop an Black Out.

Everybody has a base Alertness of 70.
132 / 70 * 100% = 189%

So you need a 89% bonus to alert.


Dictatorship gives 20%
Security Guards give up to 50%
Security Centers give up to 60% (@ 30% Centres)

Options:
Dictatorship + 49% Guards + 10% Centers = 20% + 50% + 20% = 89%
Dictatorship + 9% Guards + 30% Centers = 20% + 9% + 60% = 89%
49% Guards + 20% Centers = 49% + 40% = 89%
29% Guards + 30% Centers = 29% + 60% = 89%


Total Immunity requires 96% bonus (36% Guards + 30% Centers or 50% Guards + 23% Centers)
