I'm not wrong. I have the data to back my information.

To get the full static base deduction from SR you need to own 60% of your target's population. (base deduction is / 25) Which after 40 attacks is 1/5th of their population.

Country A:
Population: 101,773

Country B:
Population: 60,765

After 40SR attempts:
Country B:
Population: 23,412

As I've said, 1/5th. It constantly takes, each population and divides it by 25.

The same thing occurs with CD; however, fewer % troops are needed on hand. It will place your troop population to 1/5th its original size.
