  • CFC Membership Statistics---Average and Median Ratings

    Has anybody run the numbers on this. How many CFC members are there? What is the average rating of CFC members today? What is the median?
    I believe we would all be interested in the results.

    you would probably be interested in the information on this page http://www.victoriachess.com/cfc/dist_summary.php which was done a number of years ago by myself (not an official CFC project). The database and code for the database enquiries is not maintained so dynamic information from the related pages is probably not working well but the graphs and summary infomation is good.

    You would also probably be interested in this page: http://www.victoriachess.com/cfcstats/mean.php which is a page I set up for the rating auditor so he can monitor for inflation. Data is available from 2006 to whenever I have uploaded recent data (currently end March this year). Use at your own risk as not all data queries are thoroughly error checked.

        Many thanks. Very interesting.
        These stats do show a slight progression over the last three years in both categories.
        (I seem to recall several decades ago the CFC calculated the average around 1800 for what that was worth.)

          the other point for Gordan to remember is that 5 years ago, a large number of sub 1000 players were being improperly rated for active games as regular games. That is no longer true so a large number of sub 1000 players have disappeared from the averages which explains the large change is average rating for all players over the last five years.
