I agree with you that the CJK autohinter is far from perfect.
It does a much worse job in smaller sizes.

Actually, you can find the unit that does the cjk autohinting, see

http://opensource.apple.com/source/X11proto/X11proto-15.5/freetype/freetype-2.3.9/src/autofit/afcjk.c
(this is a older version though, but just give you an idea)

if anyone want to improve the algorithm in this unit, that
will be really useful.
