The September ratings have been loaded into the database and download section. Enjoy!
The ratings for March 2021 have been added for download and into the database for rating calculations and ACF rating history graphs.
The March rating have been loaded into the calculator and added to the download section. The old download plug-in I was using is no longer working in a way that I want it to so I have moved to a different plug-in. It took me a few days to populate the new plug-in with all the data of files available for download, but it is now up to date!
December ratings have been entered into the calculator and are also available for download. Enjoy!
Following the severe weather and power outages of the last couple of days the web server developed filesystem corruptions. I thought I could fix these with fsck and continue but the errors kept appearing and so I decided to reformat the hard disk and rebuild the server. That is now complete and everything should be working again. If not, please leave me a comment.
The September 2016 ratings have been loaded into the rating database for Glicko Calc and rating graphs. The files have also been added to the download section.
I also performed various software updates so if anything is broken please let me know.
Things were a little unstable over the last few days as I was trying to get the latest ubuntu version working on my server. It seems ok now but apologies to anyone impacted by the problems.
The September files have been processed and are available for downloaded in the appropriate section. Enjoy!
The June 2015 ratings have now been added to the download area and into the Glicko Calculator/Rating History database.
There was a change to the ACF rating calculation in 2003 which scales down rating adjustments for players with ratings over 2200. For ratings that are less than 2200, then the old Glicko Calc works fine. If your rating is greater then 2300 then changes should be scaled by 75% of the Glicko Calc amount; and for rating in between 2200 and 2300, changes are scaled according or a linear interpolation between 1 and 0.75.
The short story is that I have now implemented this scaling in Glicko Calc and so that facility should be a more accurate predictor of ACF rating changes for players rated over 2200.
