Could you try using the sizes of *unpacked* tarballs?
gzip/bzip2 will offset the real growth a bit (maybe even a big bit).

There were a lot of cleaning up in 2.5/2.6.

The was Bitkeeper before Git, but also the development process
has changed, with Linus becoming less of nexus of it. He does
more merges than ever now, with a large part of integration and
testing done by subsystem maintainers and people like Andrew
Morton.
Besides, you cannot ignore the developments outside of Linux
world, which percipitate into kernel (things like new architectures).
