The whole system for this is kinda bad...

Lets take an independant province as an example. Then Red Empire captures the province. This causes unrest, but patrolling takes this unrest down. The population remains without any unrest for 20 turns until its captured by Blue Empire. Blue Empire immediately marches out of the province after raising taxes to 200. Two turns later Red Empire captures back the province.

Red Empire faces massive unrest, but why? Red Empire is the liberating army, freeing the province from the heavy tax. The unrest should already be on Red Empires side, helping them to retake the province. Why should Red Empire need to do any patrolling at all?

The current system is plain broken imo, and abusing it is very very bad play.
