[Max] General Discussion / Re: Roughness implementation correct?

I'm talking nonsense - CoronaPhysicalMtl is actually a bit darker than StandardSurface.
What is odd though is that CoronaPhysicalMtl returns at F0 (furnace test, GeoSphere mesh, Base Color 0.18, full roughness, ior 1.5) less than 0.18 float.
Compared with VRayMtl here:
