"German East" everyone used for years is a great example (and we use it still, just renamed it to German_Saxony). Now when we got decent number of fully verified kits from Saxony, I can see that average wasn't good and probably included people with ancestry not only from Saxony, but other places. Nobody seems to check 4/4 grandparents in academic papers it seems, their reliability is really low.
New Saxony average we will publish soon to replace academic one (won't mix them but totally drop Leipzig academic kits) is pretty different and quite less eastern.
It's even close to "central German" genetic profile in a way, something many argued doesn't exist. All academic averages on Vahado need to be replaced with better ones, they are simply not reliable.
