If you go to http://l10n.kde.org/stats/gui/trunk-kde4/essential/ you'll see that there is an extra gray thickness in the completness column, that is not present in any of the other columns of the various tables in l10n.kde.org so it is not wanted

The code for the l10n.kde.org website is at trunk/www/areas/l10n/ in KDE svn server.

http://techbase.kde.org/Projects/kde.org#Documentation_for_Capacity links some info on how to setup l10n.kde.org
