What can I say Gq you've sparked my thurst for knowledge so I started prying around some websites and text. Found some interesting info at the good ol t-nation site. The following is written by Don Alessi and can be found here

"Pyramid and Reverse
Training Parameters:
Reps: 7 (80% 1RM) , 5 (85% 1RM), 3 (90% 1RM), 3 , 5 , 7
Rest: 180-240 seconds
Highlights: This system is a must for all trainees looking to build strength and size. The higher the average reps, the more hypertrophy will occur. I use it for at least three individual phases per year and consider it a staple.
The load increases by 5% the first three sets. This "wakes up" neural drive by means of titanic facilitation. Then the load reverses and decreases by 5% each set, allowing the trainee to expose the fast twitch fibers to a longer tension time. Beginner and intermediate trainees use a 303 tempo on these last three sets. Advanced trainees must challenge the strength curve with the use of chains, isometric holds, or five second negatives."
Doesn't seem too terribly inefficient from this stand point. So I would have to keep recommending it as a very efficient training tool until proven wrong.
