That's where I thought I'd add it- The values were already being read
for the peak meter display, so it would be convenient for the test.

Of course, its very obvious that this sort of thing is only useful on
the MAS-equipped units, but those are the only ones that are usable
right now.

I've been fiddling with some ideas for how to handle the process as
opposed to where to put it when its decided how to manage it, but
nothing real solid yet. Already shot holes in several potential plans,
however. :)
