I just have a question regarding Abyssal counterattacks.

According to this article, if a hex turns yellow or such, you can send a fleet there and clear a map in that hex to reduce the threat level by one. If the hex is yellow, clearing a map should theoretically turn it back to white. And in many cases, that's what's happened in my game.

However, there are also several times where if I clear a map in a yellow hex, it remains yellow, and I end up having to clear like 3 to 6 sorties in that map to turn that hex back to white, which is way too much. I just wanna know if anyone's figured out the actual mechanics to this yet, since sometimes hexes do turn from yellow to white with just one sortie just like what this FAQ says, while other times, it takes far too many sorties just to clear the threat.
