Wall of text but no answer still.
I will give you a hint because it's bad form to make fun of you.
You get 50 percent of your autosomes from your parent, 25 from your grandparent, 12.5 from your great grandparent, 6.25 from your great-great grandparent, now take this division to your 11th ancestor and tell me how much of their DNA you carry.
You don't understand fstats and what they mean, you just discovered your g25 child's play and you think you have a clue on archaeogenetics. Like I said, every so often there's a greek like you, high on copium, until they eventually get red-pilled on the genetic truth and leave with disappointment until we get the next one.
Modern Greeks don't have good continuity with BA/IA in terms of haplos, which is the only defining proof of genealogy, everything else is statistical inference. On PCA, South Italians and Jews are actually much closer to ancient Greeks.
You have Dacian E-V13, and Slavic I2a-din and R1a clade being a very big chunk of modern greek distribution, this is the historical reality and no matter how much you cope you can't change it, you can only continue to embarrass yourself and the rest of us who unfortunately have become a standing joke on forums, because of your antics.
