Dynamic Curve Default Settings?

What are the default settings for the Dynamic Curve Power, as well as for the Minimum and Maximum dynamic level settings? In my experimental early days with Dorico, I messed with these numbers, and I don’t know what they were to begin with. Please advise, and thanks!

You can use the Library Manager to compare your current Playback Options to the factory defaults.

These are the defaults:

Do we know why the curve power of 2.5 was selected as a default in Dorico? I’m curious, not criticizing.

I think it is related to how people actually perceive volume changes (ie. it is not linear) but I don’t don’t know the science behind it.

I faintly recall my Physics of Acoustics college course many, many years ago after reading these posts. I will need to digest all of this great info for a while as I dig out my textbook for a refresher. Thank you.
