Well, its not so much the angle itself that needs accurate adjustment, its the cross-play between both angle and offset. Changing the angle slightly (lets say its down to 0,5 degree appr.) directly changes the offset by a much bigger margin. And the change in offset is counterproductive to the change in angle.
So, lets say if you make the camber smaller, it increases the offset, while you really want a smaller offset. The way I go about it now is setting the camber of the wheel first (so that it looks good ;)), then adjust the offset by sliding the axle in the stem a bit.
In general forces due to trail offset are larger then forces due to camber... on the other hand, the arm on the camber forces (which is the trail) is larger then the arm of the offset (which is just the offset itself) Having a bit of camber on a straight bike, both the camber forces and offset forces are directed in the same direction and add up much quicker to a noticeable effect.
