March ratings and downloads update

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!

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.

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.
