None of these "recommendations" are exact, but are used because they work, and there are differences between the Schild and Andrews books.
One mistake sometimes made is to look up a torque value for a certain size and grade of bolt on one of the many charts on the internet and then tighten to that limit. That is a mistake. A certain bolt application may list a certain torque setting for a specified clamp load, but that setting may be all wrong for the application and may result in warping or breaking the part.
For myself, I just consult the Schild and Andrews books as guides and tighten to what has worked for me over the years.
