I try to follow helmet-concussion-safety developments pretty closely, and I share your skepticism that VT's testing is authoritative. More info [here](https://helmets.org/vatechstar.htm). Key point: VT "us\[es\] the methodology that MIPS uses: sticky headform, tight strap, severe anvil angle, rough grippy anvil, no neck. That methodology couples the headform more tightly to the helmet than it would be in the real world. It would be expected to favor the MIPS models, unlike the Snell Foundation's research that showed no benefit from MIPS."
