Looks good, Duke. I was wondering if the issue of correlation of measurements to subjective likes and dislikes is touched on in the chapter. In other words, if certain measurements don;t seem to have any impact on subjectie liking or disliking (in exxence are "inaudible") then should we be pursuing them. I find that aspect fascinating. I know Floyd Toole did a lot of work in this area. I was wondering if this issue is addressed by Earl. thanks -akhilesh
