Absolutely right about that, Matt, from my perspective. To further muddy the waters, naming conventions are far from it. Once, middle C was the C3 octave. Now the American Scientific seems to be winning, and it is C4. Steeped as I am in hymns, I am constantly reminded of how music has been written for choirs, which cover a wide range, although I rarely use the original score, but instead, lead sheets.
In the Key of C, in the octave C4, it is rare to see a tune drop more than two and one half steps below the first degree, meaning to a G note. Looking over my song book, it is not uncommon to see tunes with a range of seven or eight notes, occasionally breaking out above that practice for the sake of hearing the soprano. With choirs, I notice the basses tend not to draw attention to themselves. Here's another good one I came across:
