Thank you for taking the time to answer at all.

I haven't checked the algebra yet, but the end result seems to
be that this is not a bug, it is deliberate and there is a theory
behind it.  If I can work through the details, I will write it
up and post it somewhere.

Oh, oh.  If the answer is off-topic then the question
must have been off-topic, but unless I have misunderstood
the purpose of vorbis-dev, I don't see how a discussion
of an algorithm used in Vorbis and possible bug report
could be off-topic (trival or wrong, yes, off-topic, no).

Or is it off-topic because it is an Ogg algorithm rather
than a Vorbis algorithm?
