Body By Science?

Anyone here try this program by Doug McGruff and John Little? It's based on 6 compund exercises (machine) using HIT, Mentzer-esqe techniques once every 7 days.

It makes sense on one hand, because of the work taken to failure, but once a week seems like too little stimulus. I'm looking into it because my work schedule has gotten crazy and I can't always make it to the gym in my current three day split.
