Casuality Rate Boost Additive?

[Watash]

I have an Infirmary with a current level of 3 (6% boost). I also have a Composites Factory current level 5 (10% Boost). Are these and other boosts cumulative? In general are all boosts cumulative? Inquiring minds and all...

Add me if you want 435 054 538 and 884 579 865
Mid 70's level on both, tying to bulk up allies.

Those buildings boost different things, one boosts defence points, the other reduces casualty rates.

Is the recovery unit and the infirmary additive or cumulative?

I'm guessing cumulative (i.e. 20% * 20% = 37.5%), instead of 20% + 20% = 40%

First: 20%*20%=4%

Acumulative:
raw_stat*(1+0.2)*(1+0.2)

Addictive:
raw_stat*[1+(0.2+0.2)]

Accumulative > Addictive

And, Boosts run accumulatively

wtf does any of this mean lol. DC please explain what you just said in english haha

Hehe..those r math equations to calculate how does boosts work when one have both country bound, boost building.

I shall explain it in an example. Suppose one is uk flag, and have lvl10 navel research building. His battle sea units raw score r 100at/100df in total, then:

After boost= 100*(1+0.1)*(1+0.2)=132
In the first bracket is country boost, the second is from the boost building. And this type of calculation is called accumulative, namely is boosting the boosted score.

Wrong calculation is addictive which is
After boost=100*[1+(0.1+0.2)] =130 which is less that the accumulative boost.

So if u were in the middle of upgrading lvl1 boost building to lvl2. Just after u finish the upgrade, u should observe an 2% increase in ur stat.

I think you are right, it's cumulative. Otherwise we can't explain what happens when the original casualty rate is less than 20% (if additive, it becomes indestructible)
