Event for wich the devaluation is outbounding an existing level score the lowest level available (eg. level 7 devaluated by 1 is still level 7).
Older results from 2010 and older now count as 'X'.
For 2013 a pilot ranking is the sum of the two best letters gained during 2012. Optionnaly, the best devaluated letter from 2011 (or before) can replace the weakest letter.
