With wheels, its only critical to be within range and done in the correct order. Once I got the feeling of what 65-85 ft lbs feels like with the torque wrench (over several years), I just duplicate that with the breaker bar (for ten+ years). I take wheels off of my cars a lot and have had to replace lugs with worn out faces.
Consistency is much more important. You don't want a loose one and you always should check them again after test driving the vehicle.
Don't be anal about numbers when its more important to be consistent and create good habits.
