AncestryDNA Updates Ethnicity Estimates

With a five-fold increase in the number of reference samples, now 16,000, AncestryDNA has changed ethnicity estimates. There are 17 new regions. The new estimates are based on stretches of DNA rather than individual letters (A, C, G or T) at particular bases. 
If you're like me your new estimates will likely be more aligned with your expectations before DNA results were available.
My new estimate is more British. England and Wales 44%, an increase of 25%;  Ireland and Scotland 34% an increase of 4%.
There are decreases. A 4% reduction in European Jewish, 11% Scandinavian becomes 3% Norwegian and no longer any estimates for Europe West, Caucasus, Europe East or Iberian Peninsula.

What's your experience?
