I experimented with this a while back, adding encryption onto the top
(similar to compression). I wanted to to rsync backup to a remote
machine where I don't necessarily trust the security, but didn't want to
defeat rsync's diffing algorithm. There's a binary diffing tool here:
http://freshmeat.net/projects/bdiff/?branch_id=32295&release_id=151369
that you can tweak the block sizes on, and it might give you some "close
to real" numbers.

Cheers,
Mike.
