Also I don't think albedo is reflection at all, that's exclusive in refraction, albedo is the "radiation" of the sun, or light off surfaces. It allows us to see them. Other DCC use albedo exclusively for colouring, where reflections are reflections. In TG surfaces have radiation regardless of a reflection shader when there is light.
Think of a matt surface, it has radiation, buy its not reflecting/deflecting rays like in refraction.
