I disagree with the "two weeks". Two weeks of pdiff is currently
500 KB to 1 MB for sid/main. Even the complete set of pdiffs available
on the mirrors ftp.at.d.o or ftp.de.d.o currently (July 3rd -
September 29th) is *smaller* than Packages.bz2 for sid/main. 3,362,469
versus 4,376,619. Therefore using all available diffs is the correct
choice when minimizing download volume is the priority. OTOH if your
internet connection is free and fast, switching off pdiffs if
you only run apt-get update every third date is probably faster than
 ftp.d.o carries pdiffs back to the beginning of June, which are
indeed bigger than Packages.gz (about 7 MB), I do not know why. - All
/mirrors/ I checked (de, uk, at, cz, au) only carried three months.
