Instead of focusing on historical sources/events you focus on random obscure "cultures", which we know for a fact don't necessarily bring DNA changes with it. The early Bell Beakers had no steppe DNA. They were the same culture as the latter Bell Beakers who were steppe-heavy.
That's very much up to debate and more importantly, we have always look at the full package. Like the full Bell Beaker package was definitely something spread by a specific people with a specific genetic profile.
And that's what its about if connecting archaeological cultures with replacement and founder events: Not single items, but whole packages. Like for Channelled Ware in South Eastern Europe, its a whole list of newly introduced items, technologies, customs and behaviours, which in some regions appeared together with a burnt destruction horizon. In fact, in some regions, especially the Morava valley, the connection is even more clear than with the Bell Beakers in many areas, because we have actual proof of a grande scale war and invasion. The locals fled to the hills, literally, along the whole valleys all settlements being burnt and suddenly a completely new package appeared. It was a big migration period of the Late Bronze Age, with many people on the move.
And massive founder and replacement events, especially of patrilineages, don't just happen randomly, most of the time. So if we have specific subclades, specific branching events with a TMRCA, we need to find the background for it. And we already know that the previous people had not as much, if any, E-V13, because they being tested. And we already know that in the areas tested, in which Channelled Ware people/Psenichevo-Basarabi spread, E-V13 appears later. Not randomly, specifically in areas affected by these cultural formations and horizons. That's no coincidence, its a solid correlation.
Patrilineages spread primarily by conquest, colonisation and social dominance. This needs to be achieved and connected to events which can be, usually, traced in the archaeological record if they are big enough. And Eastern Urnfield/Channelled Ware was big enough, because it created a horizon which can be used for dating the region, for the regional chronology e.g. in Bulgaria. There is a time before and after it. After they appear, its the time of the beginning Iron Age. Their invasion ends the Bronze Age for the Balkans.
And E-V13 has this massive series of founder effects, like everyone can check on FTDNA and YFull, exactly in that time frame of the Transitional LBA-EIA period, between about 1.300-900 BC.
At some point, there will be a similar case being made for Proto-Albanians, but that's harder to track because it was a significantly smaller and less homogeneous phenomenon. The Channelled Ware expansion, especially of Belegis II-G?va into the Psenichevo-Basarabi horizon will create glass clear numbers of more than 70 % plus E-V13 for many regions. That's coming close to the numbers for R1a in Corded Ware and R1b in Bell Beakers.
Albanians were a much later formation with a more complex history at the borderline of two big blocks, Illyrians (dominated by J-L283) and Thracians (dominated by E-V13), which both intermixed, being later pushed by Iranians, later largely subdued by the Romans and affected by all later migrations.
In the Bronze Age however, especially for Channelled Ware/Psenichevo-Basarabi, in the initial stage, things were still more clear and differentiated. The "Roman" Viminacium samples and the "Avar" era samples from around Szeged,
both Basarabi strongholds in the Iron Age, are first but very clear hints.
