That would be dishonest. You don’t adjust input power - you adjust attenuation

EDIT if you did let’s say approximate power, or measure and present the consumed power (as some systems do) you would still be in a situation about how to present this data. Do you present your users with a simple 1-10 (logarithmic) or a 10 digit display which sweeps over vast ranges of uninteresting values.

If you opted for a more compact scientific notation … well guess what that’s also logarithmic but in two parts LOL
