That was interesting article. I read both the child and the adult version after running them through Google Translate.

Looks like the MIPS stuff likely works and likely causes no increased harm. Not so conclusive on the adult version because the clip on the POC MIPS helmet failed but still the helmet received a good rating. I'd not take either of these tests as conclusive but I think they are inferring what I was saying earlier - likely will help significantly and will do no additional harm.

The 40% claim for a reduction in oblique hits would be significant. If I remembers some of the other reading I did on this a while ago, the damage to the brain doesn't follow a linear relationship with the acceleration received but that it is much more a threshold situation - shearing (i.e. tearing of neurons in the brain/damage) is relatively small and inconsequential until you pass a threshold acceleration and which point injury increases rapidly with increased acceleration. So a 40% reduction gives you considerable margin and a chance to keep below the threshold since, conversely, if you reduce the acceleration experienced by the brain, you drop the damage in a non linear fashion too (a very good thing).

I'd love to see more testing too because if this works, I'd love to see manufacturers have to compete on better concussion protection and protection above and beyond the arcane CPSC and/or statutory standard.
