Following the publication of the new Rating Regulations which will come into effect from 1 July 2009, concerns have been raised by several players and organisers. During the 10-day working visit of Deputy President Georgios Makropoulos in Singapore with General Secretary Ignatius Leong, the following points were noted and recommended:
1. That especially for major high-level competitions, organisers normally would have an invitation list of players based on their ratings at the time of consideration and invitation. Organisers normally would have a contract with the invited players sometimes as long as one year in advance. Some players would have agreed to participate based on the ratings of the other invited players. The dynamic K=20 factor could have a major effect on the ratings of the invited players one year later.
2. The rating lists are used to seed players for the world championship cycle -Candidates Tournament, World Cup etc... The radical change in the K-factor is a major concern especially among the top players. It was regretted that parallel lists were not calculated before the decision to adopt the new K-factors.
3. The radical change in the K-factor for players rated under 2400 is also a serious concern as this could lead to an inflation for norm categories and title purposes. The potential inflation among players under 2400 will also cause a ripple effect as more players move upwards and cross the level of 2400. A study and review on the title regulations would be necessary as a result of the new K-factor - the rating scales may have to be increased.
4. Qualification Commission Chairman & FIDE Rating Administrator Mikko Markkula will produce a parallel list which uses the new K-factors (30 & 20) for tournament reports submitted from the rating lists starting 1 April 2008 till 1 July 2009. FIDE will publish 2 lists for 1 July 2009 - the normal list based on the K-factors being unchanged (25, 15 & 10) and a parallel list (known as the K-List) using the K-factors (30 & 20). The K-List will not be used but only as a comparison.
5. Until 1 July 2010, FIDE shall continue to publish 2 lists using the different K-factors. FIDE shall then review the 2 lists after 1 July 2010 - based on the recommendations of the Qualification Commission. FIDE would then decide whether to extend the trials, abort or to adopt the new K-factors with effect from 1 July 2011 as The Rating List.
