That testing process is not the end all be all, it is not perfect by any means and has some flaws. There are many threads discussing the shortcomings of their tests and lots of opinions on how much different people value, or don't value their findings. I'm sure the ones discussing the Tacks X helmet here have already decided whether or not the VT ratings mean anything to them. I've heard that CCM does their own testing (or uses another lab/University) which is more thorough than the VT tests and I'd guess their results are pretty good which is why they're expanding the usage of the 3D Printed webbing.
