git repack: --depth=100000 causing larger not smaler pack file?

  aloha!

  Yesterday I run the following command on the updated GIT respository:

    git repack -adf --window=250000 --depth=100000

  After 280 minutes or so it finished, but the strange thing was that
  the resulting pack-file was larger than before.  I had expected that
  it should be smaler, or at least the same size as before.

  kjetil git (my_next)$ ls -l .git/objects/pack/*
-r-------- 1 kjetil kjetil  2757280 2009-03-16 15:18 .git/objects/pack/pack-c5f15d5c48d6b3902a49046d7e8a8d717e167051.idx
-r-------- 1 kjetil kjetil 19961120 2009-03-16 15:18 .git/objects/pack/pack-c5f15d5c48d6b3902a49046d7e8a8d717e167051.pack

  Before I started the pack file was around 19 250 000 bytes, and was
  the result of the following commands:

  1) git repack -adf --window=250000 --depth=20000
          - not completly sure about the --window number here
          - the resulting pack file was a litle less than 19 100 000

  2) 'git fetch' to get the latest GIT patches

  3) since 'git fetch' always make an extra new "smal" pack file, I run
     the command 'git repack -ad --window=40000 --depth=10000' to be
     able to get one singel pack file of 19 250 000 bytes or so.

  I can think of one thing which is spesial with the "--depth=100000"
  number, and that is that it is now larger than the total number of
  objects in the pack, which is around 96000 to 97000, or so.

  I have run 'git fsck --strict --full' on the pack with no resulting
  error/debug output or change in the file size.

  Any help on how to debug this?
