What the ACF have also done is to run the modified system over the data from December 2000 to December 2010, recalculating all the ratings in this period. The net effect on ratings is an average increase of 73 points over the list published for December 2010. The ACF is not publishing an updated list for December 2010, instead simply publishing the scheduled March
2010 2011 list with the new ratings.
While improvement to the accuracy of ratings is good, in the short term this will cause some difficulties for tournament organisers. Some tournaments that are run in sections (eg Doeberl Cup/Grand Prix) have already advertised there tournament conditions and a number of players may find themselves moving upwards, to a higher section. On the plus side, there would be some players who may not have been eligible for some tournaments (Australian Championships, Doeberl Cup Premier) who now qualify, despite not lifting a piece for a year or 2.
