I typically shift my 928 at 2200 rpm, normal driving around town. I believe the owners manual has a limitation that states not to drive the car in gear with less than 1400 rpm. My V8 will tolerate quite a bit less than 1400 rpm in 5th gear, basically just above idle as a form of pidgin "quiet" mode. I do this for very short distances if I return to my neighborhood late at night so as to not wake the neighbors, since my "exhaust" is just shy of NASCAR spec.
Short shifting saves fuel and wear and tear on the engine, but some engines might not have sufficient lubrication to the main bearings, so it is better to wind them out a bit more, as per what Mark Howard is doing.
