That theory sounds great, but it must have been implemented rather badly. I can confirm that on my system downloading (and processing) even just three days' pdiffs takes about 200% as long as downloading the full files took before. This is on a P3 600MHz 256MB on a 2Mbit/s DSL connection. I have disabled Apt's pdiff "feature" for now.
