New vs. Old Material System / Reflection Amount

[ASIMO]

Dear Community

Since the release of the new material system with Physical material I miss the option to control the exact intensity of a reflection.

This was possible by using the Level-Amount or even apply a color in the Reflection Tab in the Old System (Legacy Material)

It was possible to create surfaces that have 100% Glossiness but would reflect only 50% if needed. IOR would stay the same.

This was helpful for less reflective glass surfaces to create an anti-glare effect for switched Computer or Tablet screens.

How would this be correctly done in the new system ?

What is the logic behind it ?

Thank you for your feedback :)

Logic is probably not the most successful :(
And you are not the only one...

As I see, logic and models present are:
- 'Standard Physics' for "New"
&
- "Game Theory" for "Old".

Both co-exist NOW. 
Application, of one or other, is up to user awareness.
