I think it’s totally important to still remember that all of these helmets still meet many of the same safety requirements - meaning that none of them are downright unsafe or bad helmets. Others may just be better. And, a well-fitting helmet will always be a safer choice than one that does not fit well.
That being said, I am quite surprised with the results, especially that many MIPS helmets were ranked lower than their non-MIPS counterparts. And that the relationship between helmet price and ranking is all over the place. Cool stuff, and I’m excited to hear the discussion that comes out of it!
