Under quality 6, encoded through CDex from same source cds as quality 10, on the fly not checked (i couldnt find the Hybrid Theory album), first few seconds of each track compared to quality 10 track (bear in mind i'm using 13 year old, but extremely high quality stereo system since i dropped my semi-decent monitor headset & ripped off the right phone in a fit of frustration of not being able to reattatch it properly):

Macross Plus OST ~ for fans only totals 59.8MB (no discernable difference, each file is roughly between 60% & 70% of quality 10)
Discovery totals 86.4MB (no discernable difference, missing seconds on start of file have been encoded this time, each file is roughly between 60% & 70% of quality 10)
God Hates Us All totals 60.8MB (no discernable difference, and i'm seeing a pattern with the file size)
Majoras Mask OST disc 1 totals 79.8 MB (can't be bothered to listen now)
Majoras Mask OST disc 2 totaled 172MB under quality 10
Majoras Mask OST disc 2 totals 77.1MB under quality 6
Jagged Little Pill totals 74.6MB (cant be botherd to listen now)
The Marshall Mathers LP totals 89.1MB  (can't be bothered to listen now)

<p>about the bitrate peeler thing i've mentioned somewhere- it'd make doing comparision tables easier as well wouldnt it?

you know, usually, you have to encode once per quality setting, but with bitrate peeling (as i understand it), you'd only need to encode once, then just peel from the highest quality then keep going (either from the previously peeled file, or from the parent file)
