use entropy to get entropy of a file
use fsde to transform a file
use entropy to get entropy of new file...
gives slightly better compression.

Try customising FSDE, it's set at 200K blocks, 4096 occurences and order-25
contexts, try using 50 occurences and order-4 contexts. Or try big block
sizes with big occurences and context orders (250).
fsde fudges up the ends of files.
