How is using bits any more daft than using decibels when you wish to express
a log ratio?

It's just a constant multiplier different, and arguably more intuitive to
those intimately familiar with bits and bytes.

dB = 20 log (Va/Vb),  bits = log(Va/Vb)/log(2) so bits = k* dB
where k = (1/20)/log(2) ~= 0.166  ~= 1/6

Hmm.. that's pretty easy to remember.

;-) ;-)
