Hidden MBUX screen volume settings

When driving, the speed dependent volume on my GLS gets too soft when slowing down. I am constantly having to play with the volume control. I have adjusted the user access screens with little success. I called up the hidden Dealer Mode screen which has a lot of volume settings but cannot find a good explanation for the rather arcanely worded settings. Does anyone have a link that would explain these so that I could better tune the speed variable volume?

I guess I look at the speed dependent volume opposite from you. Consider the baseline to be stopped. The setting should then adjust how LOUD the volume gets as you accelerate and he cabin or road noise increases. Then when you slow, it goes back to your baseline.

Either way it's the problem. Setting low, stopped for comfort results in too loud as overcompensates for high speed noise level; comfortable high speed, then too low slowed down. I know these Dealer Volume settings would allow me to adjust the volume curve but I can't make good sense of the terminology and got nowhere just playing with the settings. I can't even seem to turn off the cursed feature.
Maybe someone could post screenshots of their settings that seem to work well.
