I just restored my SL volume to an empty volume (with the "Erase...." box checked), and the sizes of the source and restored volumes are wildly different. (I got almost identical results from a second try.)
Source volume:
Artie-s-Computer-4:~ artie$ sudo du -xhd1 /
Password:
40K /.fseventsd
31M /.Spotlight-V100
0B /.Trashes
0B /.vol
882M /Applications
3.9M /bin
0B /cores
4.5K /dev
1.0K /home
1.5G /Library
1.0K /net
0B /Network
729M /private
2.6M /sbin
1.7G /System
184M /Users
379M /usr
4.0K /Volumes
5.3G /
Artie-s-Computer-4:~ artie$
Restored volume:
Artie-s-Computer-4:~ artie$ sudo du -xhd1 /
Password:
336K /.fseventsd
37M /.Spotlight-V100
0B /.Trashes

Artie-s-Computer-4:~ artie$
Does that Terminal output make any sense to anybody, or do I just not particularly understand what I did?
Thanks.
