I've watched the video a couple of times and it's definitely not front on, like the new tests. I'm sure Ayrtek will be all over it, because , well, they have to.
Looking at it objectively, the two things that occur to me are that:
1. Off a top edge, the ball is spinning violently.
2. The ball seems to pass through very easily.
The best guess I can come up with is that in these circumstances, either one or the other of the ball or helmet /grill combination has momentarily deformed.
As Dave has said, the standards and a helmet go only so far. They are better than nothing, but 100% protection is highly unlikely.
Let's wait for the Ayrtek review....
