Subversion adoption data for 2006-2008?

Sorry for the off-topic post. I'm doing a presentation on Subversion,
and want to present accurate data on concrete Subversion adoption.

I've been looking at the graph at http://subversion.open.collab.net/subversion-adoption.html
  and used the data I could find at http://www.securityspace.com/s_survey/data/man.200707/apachemods.html?mod=U1ZO
  but it stops at August 2006, and I can't find any data beyond that.
Does anyone have adoption numbers available for the period from
September 2006 to July 2008?

In case anyone wonders, the graph is decent-enough looking, but it
really doesn't fit in the scheme of my presentation, and I'd like to
be able to resize it without artifacts.

Thanks in advance—you can email me off list if needed.
