Yes, and if you do a bit of googling you will see its putting some odd brands (Marushin) on top marks and giving middle marks to more recognizable brands(Suomy, Shoei). They test some very specific points and so the conjecture is that some manufactures are gaming this and strengthening in particular areas. So there is a bit of controversy out there on this. I took a look though for my new helmet and it got 5 stars, so I was happy
Like all things, its one source of info, but wouldn't use it alone to make decisions.
