As you can see from this lovely chart from Samanna's Reference Desk:
http://samanna.net/gen.info/faction.shtml
What are the Faction standings?
Ally = +4 1450 to 2500
Warmly = +3 1100 to 1450
Kindly = +2 750 to 1100
Amiable = +1 150 to 750
Indifferent = 0 0 to 150
Apprehensive = -1 0 to -150
Dubious = -2 -150 to -750
Threateningly = -3 -750 to -1100
Ready to Attack = -4 -1100 to -2500
It takes a long freaking time to get out of Dubious.
