   I suppose the original packages tar file ontains the documentation files
   uncompressed whereas the .deb package installs these files as
   compressed.

   So they are compressed in one gzip run in the .tar.gz, whereas in the
   .deb case all files are compressed individually and then compressed
   again by dpkg --build. This makes the overall compression less
   efficient.

No. They are just copied, along with a 16kb copyright file and a 169b
changelog.Debian.gz file. Then dpkg --build is called. Maybe the fact
that there is a .gz file at the start of the archive makes the overall
compression less efficient, but this is strange.

YA.
