This ratio is more akin to musical dynamic range. It just looks at the waveform properties and doesn't depend on the recording medium itself. Although musical dynamic range is something more like the maximum RMS level divided by the minimum RMS level.
But yeah, they're all good was of looking at it. Just depends on what property you're interested in.
