Are DBD addons additive or multiplicative?

I was watching a vid of inter3ct (a famous dbd data miner), and He went on to mention on how some perks are multiplicative with each other, but additative with status effects and other complicated stuff.


I wanna know about addons, I'll give an example below to clear it up

Wraith Base cloaked movement speed is 126%

Yellow windstorm boosts by 15%. Green windstorm boosts by 20%. Purple windstorm boosts by 25%

So let's say I stack purple and green.

Is it 126 * 1.2 * 1.25 = 189%

or

126 + 20 + 25 = 171%

I hope you get the point, and I hope someone out there has the answer :)

    I don't think anything is multiplicative in this game... it's all additive as far as I know.

    I think all modifiers are based off the 100% values and not the current value before applying the modifier so they are additive.

    For example when you are calculating killer movement speed, it's always based on the running speed of survivors (that's the 100%) and not on the default unmodified speed of the killer. Therefore if srs = survivor running speed:

    Wraith's default cloaked movement speed is 1.26 * srs. Yellow Windstorm addon is +12 % according to wiki.

    1.26 * srs + 0.12 * srs = 1.38 * srs or 138%.

    And not:

    (1.26 * srs) * 100% + (1.26 * srs) * 12% = (1.26 * srs) * (100% + 12%) = (1.26 * srs) * 1.12 = 1.4112 * srs or 141 %

    I hope that covers the mathematical part of it.

    I got the idea that in general positive modifiers are additive while negative modifiers are multiplicative.
