The I2a-Dinaric theory can be put in the trash receptacle, as evidence is strong that this haplogroup was brought to the Balkans pretty much exclusively by Slavs. It’s not indigenous to the Balkans.
As a layperson who never toyed with amateur gene modelers like G25, I too have to be careful when seeing them. For example, there is an Anthro-type model of modern mainland Greeks that shows them to be more Anatolia MLBA-like than Empuries and Mycenene. What is this based on, the rumor that some classical Greeks are Cyprus/Anatolia-like? That leaves out a lot of other Greeks, and is not based on any published data. It looks like an assumption. Plus, the Peloponnese study shows those Greeks do not have much Asia Minor admixture. That was part of the theory that Asia Minor people were brought to replace the Greeks who disappeared after the Slavic invasions.
Using Apulians as a source pre-Slavic era (400-500AD) northern Greeks, which can be accurate you get 35% Slovene, slightly above 5% Armenian-like ancestry and +55% Apulian.
