It seems Marmot uses this for comfort levels of their bags. Researching their 0 degree bags they have different levels according to this standard.

Comfort:18.3F / -7.1CTransition:6F / -14.1CRisk:-30.2F / -34.1C

Comfort:12.2F / -11.1CTransition:1.6F / -16.1CRisk:-40.3F / -40.1C
So it seems even though the bags are rated for the same temp the Couloir is more "extreme" or "robust". This would make sense as the fill power used for it is lower but it also weighs more.
So why doesnt every company use this and is it accurate?
