I have 2 engineering Degrees myself. Regis College of Denver and From Trenton State. The problems I have seen are absolutely install and concrete company related. The "System" is great in theory
I believe a bad installer of a block wall can still mak wall that wont collapse but a bad installer of a superior wall can cause much more serious damage.
When the superior wall installer made the garage wall system, he had no extra reinforcement between garage door bays. The garage door headers send all their weight down between the doors. The entire weight of the building sat on a sill plate and 1.5 inch of concrete wall. I had to dig it out, scratch out the foam and fill the area with concrete or risk a collapse. I was not involved until a fews weeks after the walls were installed so I never saw the plans...
