I subscribe to most of Gary's techniques. However three shim points per side seems a bit light to me. As a rule I place shims at the hinge points and the space between hinges to ensure a consistent reveal between jamb and door. Further I place shims at the head of jamb where rabbits on jamb legs and head meet and at the center of head. It appears that the author is relying soley on the case work to hold the jamb reveal true. This techique is quite common in track or production work.

I never use pre hung doors and opt to field hang everything. It gives one the most control in dealing with pre existing "challanges".

It all comes down to what your comfort level is and belief in you own tried and true techniques.
