If I remember correctly, various discussions about this topic resulted
in two things:
1. There will be another tuning round for Vorbis eventually, but it's
not top priority at the moment (Vorbis is good enough for most people
the way it is now, and there are more important things at hand, for
example libogg2 and Theora).
2. To really help Monty fix things, he needs hard data, not anecdotes.
Many anecdotes (more problem samples, more descriptions of the same
problem, etc) don't help, i.e. are not useful data.

Admittedly, I don't really understand/know what he really needs, and I
kinda doubt that I, for my part, can provide it. Maybe you can tell some
about it, Monty?
