I've been tracking the Sarge cds and dvds for i386, and dvds for powerpc for 
months now. It seems to top out at about 10% by package count or lately 
rather less. Recently the i386 cd images have been entirely rebuilt from the 
updated dvd isos, ie no download at all.

The normal order of update on the jigdo mirror is i386 dvd, powerpc dvd, then 
i386 cd. I could reduce the download somewhat for powerpc dvd if I used to 
i386 dvd iso as input to powerpc but my scripts do not use that source.

FWIW about 25% of packages in Sarge are common to all architectures.

Hope that info helps.
