Specular value in Glossy material

[medzo]

Hi

This may be a strange question, but it is bugging me for a while now.

Why is default value of specular in glossy material 51,51,51?

Is this a correct (realistic) value and all other values are just for artistic reasons?

I heard somewhere that in PBR rendering specular value for dieletrics should always be at 50% so in octane it should be 128,128,128?

Thanks

Nobody knows?

To be honest, I can't remember it. Probably 0.2 (as a float value) was the default setting in the Octane 2 Standalone or something like that. Now the default value is 1.0 (full white) in Octane Standalone 2018.1

Thanks,
