Well, I clarified that peeling by, say, 30% works fine/satisfactory already.
This is enough for making your files a little smaller for listening to them
on your handheld devices.
If I understand correctly, Monty talked about using different encoding

easier. This is all _encoding side_, so yes, only newly encoded streams will
reap the benefit of this.
