    Yes, but it performed slightly worse than xz, most likely because it uses the same compression algorithm.

    -rw-r--r-- 1 469K 10 Sep 19:33 accel_packed.7z -rw-r--r-- 1 559K 10 Sep 19:33 accel_packed.bz2 -rw-r--r-- 1 559K 10 Sep 19:33 accel_packed.gz -rw-r--r-- 1 468K 10 Sep 19:33 accel_packed.xz -rw-r--r-- 1 560K 10 Sep 19:33 # Uncompressed file, packed with Csss/CLsss: -rw-r--r-- 1 701K 10 Sep 18:34 accel_packed.dat

    These are all about +/- 10%. Unless there's a significantly different and amazing general compression algorithm I haven't considered, I would imagine these results won't improve much, which is why I'm asking here to see if there's a way I can further optimize the data itself.
