Thanks for your interest.
However, gzip is in maintenance-only mode.
There are far better free compression tools (http://tukaani.org/xz/),
and I am working on gzip solely to fix bugs and maintain a certain
level of portability and robustness.

I'm sure that if you can improve upon xz's overall compression performance,
its author would be interested in integrating your improvement(s).
