Well, most of historical Russian areas belong to the Central Federal District, but that is a pretty expansive territory spanning different pre-Slavic substrates. E.g. you can see that Tver resembles Kursk (which is significantly to the southwest) rather than Murom (which borders Moscow on the east). Although maybe that's the sample being used.

Tver is 21, Yaroslavl and Ivanovo is 25. They seem fairly distant, with Yaroslavl being about halfway between Tver and northeast Russia, while Tver is roughly halfway between Yaroslavl and southwest Russia.
Those are my Tver grandma's Dodecad K12b components. She is right from the centre of the oblast, between Rzhev and Tver: Grandmother1,2.06,0.9,0,0.67,17.59,64.69,0.79,0,1. 32,0.53,11.45,0
