This (the ethnicity breakdowns) is all a pretty new field and as such is still evolving. I really wouldn't put too much stock in them. See http://www.legalgenealogist.com/blog/2013/10/27/those-pesky-...

My own percentages have changed a lot since my first test (I was on the initial beta group), and event he new ones seems "off". You do not inherit DNA equally from all ancestors, and although your paper trail might show a specific breakdown it is not necessarily going to be that in your DNA.
