Unrest formula(e)?

[Aleph]

Hey all - just wondering if someone who had looked at the back end of the formulas had a sense for how much unrest is caused/prevented by what level of taxation? The game is very clear about how blood hunting generates unrest, but not very clear about how taxes reduce or generate it.

Basic Q: If I have 30 unrest, 3 bloodhunters, and 0 taxes, can I hunt with one and still hope to hit 0 unrest?

Advanced Q: If I have X unrest, how many turns will it take for 0 taxes to eliminate it?

Thanks!
