Not really accurate.  Since the rpm archive is compressed with gzip and
to my knowledge we do not have the rysncable patch in our gzip (nor does
rpm use it) the only data which can be saved from being downloaded is
the headers which are not compressed and do not always change much
between versions.  However the headers by far are the smaller part of
the package.  

This document by the rsync author (which happens to talk about Debian
but the same issues apply to rpms and Mandrake) covers the issues
nicely:

In short the solution to this problem goes far beyond having a system to
rename the files so rsync will resume the transfer...
