Yea I know (and knew) what you were getting at, it's just that when reading that introduction of yours one would think that wv wins a considerable amount of the points you list subsequently. Had to defend poor flac

Using flac at level 8 is a waste of cpu cycles imo. Compared to 7 or even 6 you only win maybe 1-5(-10?) kbps, at the expense of an insane encoding time.
Check out the lossless codec comparisons linked to from the HA wiki, they have some nice stats and graphs on compression and decompression speed. The WavPack stats might be outdated on several of them, but other than that you can draw some interesting conclusions. For example
this page is one indicator for me that using flac at levels above 4 or 5 is not too sensible unless you need to squeeze that last bit onto a medium.
Oh yes, as you can see Shorten is still faster than wv and flac at these levels - and considerably less efficient.
