How do I love thee (USSC data), let me count the ways (to sentence)

I noted here that I was hoping to see some US Sentencing Commission data on whether the Gall and Kimbrough rulings might be having a big impact on district court sentencing outcomes.  Joyfully, the USSC today scratches my data itch with the release of this new data report, which is descibed this way on the USSC website:

February 2008 Preliminary Post-Kimbrough/Gall Data Report:  A set of tables presenting preliminary data on fiscal year 2008 cases sentenced on or after December 10, 2008.  The numbers are prepared using data received, coded, and edited by the Commission by February 21, 2008.

In addition, the USSC also now has available its official 2007 data sets:

2007 Annual Report and Sourcebook:  The 2007 Annual Report presents an overview of major Commission activities and accomplishments for fiscal year 2006.  See the Commission's 2007 Sourcebook of Federal Sentencing Statistics for descriptive figures, tables, and charts, and selected district, circuit, and national sentencing data.
