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.
