I noticed that my subclanks were four lower than my FDC-RAC. The 'oldest' four of my clanks however are GoofyxGrid, that are older than a month. The same I noticed for people who are new into displaying their WCG badges. For all those badges they get a FDC-RAC too, but it is for results older than a month, so they do not count for their subclanks -at least, that's my conclusion, I have a special interest in subclanks.
