Depends on who's running the wrench, I think. Some people have no sense of physical perspective and will, in fact, over do it if they're strong enough.
Based on my experience with the torque wrench, however, you're correct that when it starts to click and grab, you're right about at 40 lbs., so I'd say that's a good guideline.
