"Northern" Admixture in mainland Greeks

[Kari]

The DNA of modern Greeks has been influenced by the migration of the Arvanites,Slavs,and in a smaller degree,Celts and Germans.To calculate the "Northern" Admixture,
I created a 2-Way Model using Byzantine Samples from Balikesir representing Aegean-Anatolian ancestry,and South Slavic medieval samples from Montenegro representing that "Northern" Admixture.
2-Way Model:

To calculate the Slavic Ancestry,I used another 2-Way-Model,using Sicilians as Aegean-like,and Estonians as Balto-Slavic

For the Celtic ancestry,i used Sicilians as Aegean-like,and Irish People representing the Celts.
After i took off the Slavic Ancestry that is captured by the Irish.
Peloponnese:1,2%
Central Greece:2,4%
Thessaly:5,6%
Epirus:5,2%
Macedonia:3%
Thrace:2,2%

For the Germanic ancestry I used Sicilians again,and Norwegians representing the Germans.
After I took off the Slavic Ancestry that is captured.
Peloponnese:1,4%
Central Greece:2,4%
Thessaly:4,8%
Epirus:4,6%
Macedonia:2,8%
Thrace:3,2%

In the end,Ι got the northern admixture,and I took off Slavic,Celtic and Germanic Ancestry,
to find the Balkan(Illyro-Daco-Thraco-Pannonian etc) Admixture.
Peloponnese:17,6%
Central Greece:17,4%
Thessaly:14,8%
Epirus:18,8%
Macedonia:20,2%
Thrace:27,4%

Samples I used:

I guess that your method could be more accurate if you use Ancient Samples.
Mycenean Greek
Italo-Celtic(Tumulus+Aut-La Tene) as Proto Italo Celtic
Gordium IA as Anatolian IA(Roman Imperial Era influence)
Slavic as Medieval Slavs from Ukr and Rus
Germanic as DNK Germanic or something like it
I would add some extra Paleo Balkan but I guess it will merge with Mycenean.

Proto Italo Celtic could been either Doric Invaders(Illyrian-Like Urnfield Minor+Paleo Balkan) or Some later contribution.
Slavic ancestry is higher than this model, as you use Sicilian like proto Greeks, what is completely wrong. Similarity doesn't mean same origin
