Overdose perks

I was wondering if the 30% overdose reduction stacked with the 50% od reduction to make 80%? Or is it like the edu (with merits, city job passive, and WSSB BB reduction)? Where it’s actually 35.2% instead of 40%.

my question is if the od perks stack in the manner to make up 80% or stack in the manner such as edu does.

I believe it works in the same way as the educational reduction stacking.

What 50% od reduction?

7* Nightclub has a 50% OD reduction perk.

Also does anyone have any research regarding this? Has anyone done some testing? With a base 3% OD chance, with faction 30% reduction that goes down to 2.1%, while in a nightclub it goes down to 1.5%, with both it'd either be 1.05% (multiplicative) or 0.6% (additive).

!!! right my bad.

my money is on multiplicative

additive seems too OP

where's Andyman

What would be a good way to test this anyway? Get two groups of people, one in a 7*NC or better, both in a faction with 30% OD reduction.
Control their xanax intake for a week, determine their average OD rate, with two groups of 25 taking at least 2 xans per day you should be able to get some decent results...
