No, that's getting the customer to speak *your* dialect!

People are notoriously bad at gauging differences in "volume levels",
"light intensities" -- even speeds and weights (less so) WITHOUT some
numerical indicator that they can consult.

Tell the person closest to the "stereo" at a party that the music should
be "twice as loud".  What do you think he will do?  Move the volume
control from "3" to "6"?  What if the control isn't labeled?  Or, if there
are "VU" meters on the front panel?  Chances are, he'll just cautiously
bump it up and look back over at *you* for confirmation.

Likewise, tell someone to make the lights "twice as bright", etc.

They don't care about the resistance between the wiper and the end
terminal; or the overall gain; or the average voltage across the speaker;
or the current through the lamp filament; etc.  That just adds another
issue that you have to explain.

Even traveling on a roadway it's hard for folks to gauge their (instantaneous)
speed relative to some "reference" speed -- unless there is some "regular"
feature that they can observe in passing (e.g., the stripes on the roadway).

Instead, think of how an "average idiot in the street" would describe
the action (i.e., perceived results) of a "non-linear" control.  Then,
turn the description inside out for your "proper" control.

"Can we make everything louder than everything else?"
