Source? I totally disagree and as far as I'm aware there is no evidence provided which supports that theory. The only studies I've seen in fact directly contradict such a finding.
Excuse me but 10mm all round equates to a 20mm diameter increase. Fire a 20mm larger projectile through a forrest and you proportionaltely increase the likelihood of striking wood. Simple maths.
Source is pretty basic physics. You will find supporting evidence in any Physics textbook. Increase the time of the collision via padding, and the force is decreased. Glancing blows that shear the edge of the helmet which would otherwise have missed aren't going to cause concussion.
