In the Edelweiss home, it is said that two layers of strapping prevent thermal bridging. Albeit, the screws from the second layer of strapping do not go directly into the studs, but they still go directly into the first layer of strapping which is itself directly screwed into the studs. So there is still some thermal bridging. Did the software analysis however prove that this indirect degree of thermal bridging is so elongated (from outer screw through inner strapping to inner screw to stud) that its net effect it so greatly reduced as to be neglible?
