Seems a lot of work for an intuitive result. If a wall uses only 50% of the material per linear foot and is less than 200% length, well duh it's going to save bricks.

Though depending on the wall the precise savings may be different, in a flemmish bond some bricks are laid header out (spanning the two bricks) where it looks like the model is just 2 offset walls side by side

I also think the strength test is missing the point. any focused damage is likely to be more severe on a thinner wall, period. But I believe you can make a crinkle wall of relatively arbitrary length with decent height whereas an buttressed straight wall of sufficient length might be something you could practically push over with your hands.
