I haven't done any tests yet, but it seems to me this method is unnecessary.
The reason it doesn't work ok on formal .debs is because they are
compressed. Just doing:
ar x file.deb
And running xdelta on the tar files, should be sufficient. Can you let me
know the set of packages you tested it on that got 40%?
