Main reason I disagree with this is just today a faction who owns:
- No planetary facilities
- No starports
- Is only present in one system
- Has only =~ 5% influence
... went into outbreak.
You might need to elaborate more on how you think Biowaste missions trigger outbreak. There's literally no way to interact with this faction other than by killing their ships, or running missions for them. If doing biowaste missions causes the faction you run them for to enter an outbreak, that seems a bit... obscure? (i.e shipping biowaste to <a different place> triggers an outbreak in <the system that no longer holds the biowaste>. It's fairly bizarre...)
i think, "trigger" is a bit to strong. i would say it like that: biowaste missions add to the outbreak bucket. mission effects are always apllied to the mission issuing system niw(which doesn't always makes sense).
an outbreak bucket gets filled over time, with multiplier between 0 and 1? for (hidden value) standard of living. war/civil war/civil unrest do lower standard of living. bucket is countered by medicine trading, and emptied half if any other state goes active (backed by dev quote).
how to test that? search for a minor faction in some backwater system without traffic, but a market. sell biowaste till they get into outbreak. hopefully you don't trigger boom. after outbreak has ended (and iutbreak bucket is empty) count the days till outbreak reoccurs without any traffic. after second outbreak has ended, trade biowaste. compare.
... sounds like a half-a-year project...
