If you or a friend are handy with statistics and a spreadsheet program you can use the ratings lists to generate your own analysis.
For instance, Steve Eddins created some graphs based on the June 2008 list. See his blog at http://www.eddins.net/steve/chess/2008/06/06/131 to check it out.
For those who don’t have access to rating lists…. You’ll be a better player for knowing the rules deeply, and more TDs are simply a good thing for your local chess community.
