Hello there,

Please find below the "mean time to happen" section of a custom event I'm working on that's meant to simulate the first step of discontent in a region that's of a different culture, that is to say the first step towards independence of a region that's being neglected. This is accomplished through measuring the "neglect" of provinces within that region via revolt risk.

The mean time to happen is 15 years, and the base requirement is that one of these provinces have a revolt risk greater than 5. That means that if those provinces have a revolt risk of 5 for about 15 years, the event will fire. Nice!

What I want is to make it so that higher revolt risks will make this event fire faster. We can accomplish this through mean_time_to_happen modifiers. However, here is where I run into problems: do these modifiers stack, or not?

If they do stack

modifier = {
        factor = 0.5 # 7.5 years (15/2)
        any_owned_province = {
            AND = {
                culture = sahrawi
                revolt_risk = 7
            }
        }
    }
    modifier = {
        factor = 0.5 # 3.75 years (7.5/2)
        any_owned_province = {
            AND = {
                culture = sahrawi
                revolt_risk = 8
            }
        }
    }
    modifier = {
        factor = 0.5 # 1.85 (3.75/2)
        any_owned_province = {
            AND = {
                culture = sahrawi
                revolt_risk = 9
            }
        }
    }

If they don't stack

modifier = {
        factor = 0.5 #7.5 (15/2)
        any_owned_province = {
            AND = {
                culture = sahrawi
                revolt_risk = 7
            }
        }
    }
    modifier = {
        factor = 0.3 #4.5 (0.3 * 15)
        any_owned_province = {
            AND = {
                culture = sahrawi
                revolt_risk = 8
            }
        }
    }
    modifier = {
        factor = 0.1 #1.5 (15 * 0.1)
        any_owned_province = {
            AND = {
                culture = sahrawi
                revolt_risk = 9
            }
        }
    }

TL;DR; if they do stack you just repeat the same modifier factor over and over, if they don't stack you need to increase your modifier factor otherwise all 3 conditions will give the same amount of time reduction on the event

Thanks for your help!
