I like this, very much (FWIW).
Not least because it provides a little meta-analysis of the data: to wit, the
distribution of quality across the population of tested devices.

Biased towards the
excellent/very good, but far from normal (or even Poisson), and far from monotonic -- with a long, lingering tail of losers.
In fairness, the current graphic conveys the same information but in a less obvious way
Adding the third dimension of
price to the meta-analysis would be tonnes of fun to look at!
(I guess one could calculate a SINAD per dollar ratio and just look at that)
