This was worrying, as a Spesh Ambush owner...
I know there are many ways to test a helmet, but seems decent.
What amazes me is the variance between two models from the same brand. Also seems that cost doesn't buy a high rating. Fascinating.
Bizarre that they don't use absolute measures for their recommendations.
Interesting thing about that is that a fair few results are completely at odds with the quite well regarded Virginia Tech test results.
The POC Tectal Spin, for instance, received a not-exactly-glowing result, but gets the maximum possible rating in the Virginia Tech tests
I think the main thing it highlights is that there's no standardisation of tests whatsoever.
ROTATIONAL INJURIES!!!!
Bizarre that they don’t use absolute measures for their recommendations.
A bit odd. The only exception to all the recommended being >=18% is the Bell Trace. All the others get the recommendation the score would suggest. Weird.
I find it more interesting from a scientific testing point of view than a helmet performance point of view.
Few things to consider:
Are the tests relevant. What validation have they had based on real world examples.
Are they comprehensive. Did they omit a test that is significant.
Is there any bias in the testing (who pays, who does the research and why).
Standardising of tests is nearly always a good thing. It is likely to be possible across the EU. No idea how we will interact with regulations in the future. Getting agreement from the US is nearly impossible. They are big enough to go alone and often do. ASTMs are often pretty close to EN/ISO standards.

It does say in the notes that they were above average in shock abortion and to be recommended it had to be below the average in both sets of tests.
How long have I been banging on about oblique impacts needing to be tested?
Testing of helmets indeed almost all "research" on helmets is pretty crap
Even these have serious limitations. I might dig out the full paper but it seems they just use a headform in the helmet not a whole body dummy
