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.
March ratings have been entered into the calculator and are also available for download. Sorry for the delay and hopefully the calculator is useful for those people competing at Doeberl Cup this weekend.
December ratings have finally been added. Sorry for the delay.
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.
The March 2015 ratings have now been added to the download area and into the Glicko Calculator/Rating History database. This was a bit delayed on previous cycles mainly due to an website stability issue which I have been trying to get sorted. Hopefully this issue is now fixed and the site will be more reliable and ratings have been updated too. Apologies for any inconvenience caused by the site stability or by the slow updating of ratings.
