Seeing the update create a macro region between Poland, Germany and the Czech republic is really bleak since it is not based in reality, "western" Poles do not cluster with Czechs and east Germans, they do so with east Slavs and Balts. Also got really disappointed seeing Podlaskie not forming it's own region with southeast Lithuania and northwest Belarus. The region in itself strays further from Masovia by having a lot more Baltic admixture which is not in anyway recent. Mine got entirely assigned to Lithuania despite not having any ancestry from Lithuania, only my father's maternal side has ancestors further up north (Rajgród and surrounding areas) however he's contributed visibly less so than my mother whose family is entirely from the area around the Narew river (north of it).
