Extra points on the clan list

I keep meticulous records of my own clans performance for my clan newsletters and alway check my figures against the site clan list.
We seem to have been awarded an extra 2 points and an extra draw.
The numbers agreed on (and up to) March 7th and all the other numbers agree (games outstanding etc)
Has anyone ever notice any errors of this nature before?
Not that I'm complaing.....
