I think you're talking about average compression ratio because it
depends on the particular sample.  to make significant improvements
(>3%) would require changes to the format that wouldn't work with
older decoders, which I don't plan on ever doing.

if you look at the comparison here:
you will see that FLAC is already within 3-4% of the most aggresive
