I know that I'm going a bit on a tangent here, but you are right. The
human relation between two different stimuli and their perceived
difference is not linear but logarithmic.
For example, a sound of 20 dB is 10x louder (log) than a sound of 10 dB
in terms of physics, but to our brains that process it, it sounds only
two times as loud (linear).
I hope that it's not getting too technical...
Anyway you can argue about if its log2 or log10 or something else, but
that's just a detail.
