Ok, I've changed the projects it analyses per your recommendation.
Also I've made it print the cut off date I used to assign blueprints
to the "early" or "late" creation date buckets

I won't include the other projects in this mail, but you can see them in
the blueprint-summary-XXX.txt files here:

  http://berrange.fedorapeople.org/openstack-blueprints/v2/

there is some a bit of variance between projects, but they seem to
mostly fit the overall picture. So I don't think one project is
particularly better or worse here.

Daniel
