What kind of number do you want?

Before that change I wasn't able to repack an already tightly packed (about 340MB) gcc repository on my machine while the same but sparsely packed (3GB or so) repository could be repacked just fine.

I have a test Mozilla repo dating back to the time you were playing with it too (I think). Its directory date is 2007-04-12. It was quite tightly packed already, but I just ran a "git repack -a -d -f --window=100 --depth=2000" on it and now have a 380MB pack file for it.
