Looking at the project maps for all the main R1b clades, its clear that there is an important block of Europe that is very undersampled - central Europe. All the ptoject maps show very very few hits in Austria, the eastern half of south Germany as well as Czech republic and eastwards.  While all the ex-beyond the iron curtain countries share this lack of sampling, the lack in Austria and neighbouring bits of south Germany is especially odd.  Is this simply because this is a very land locked area and didnt have a lot of immigration to north America?  For this reason, I think we can clearly gain positive evidence/prove presence  but we have to be a lot more careful in how we percieve negative evidence/absence while testing largely remains funded and ordered by north Americans of European descent.

I agree that this is a tremendous problem. Central and Eastern Europe are grossly under represented.

The British Isles are grossly over represented.

The German sample, which is not over represented relative to the database as a whole, has its own over represented element - the Rhineland - primarily because that is where the big influx of Germans into Pennsylvania and New York in the 17th and 18th centuries mostly came from.
