I don't understand how the suggested waveform could be very accurate
until the session is complete due to the effect of automation on the
output wave form.

Once I'm done working on the music and things don't change anymore it
could be a good waveform, but in the process of making the mix I might
be dragging automation points around which could invalidate what's
shown in that display. Ardour could render it in real-time but I
wouldn't want it wasting CPU cycles each time I tweak some automation.

This would even be more suspect should Ardour ever handle MIDI, but of
course I started asking for that in maybe 2000 so I don't suspect we
really have to cross that bridge quite yet... ;-)

Not a big deal and I do see how it might be helpful in your application.
