I'm still not convinced it's 9% - one thing I am certain of is that we will not heal any more before the barb attacks... (Civ4 heals at start of turn, always, for some crazy reason). In other words if he's at 65 right now he'll be at that when the barb attacks... won't be 85 until our next turn (if there was no barb) But it seems we decided to wait and be safe anyway, that's good.
