Power outage and corrupt filesystem

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.

March ratings

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.

Glicko Calc updated

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.

Enjoy!

March 2015 ratings loaded (finally)!

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.
