Eastern Bulgaria has a definitive Turkish majority with a ratio of 80% to 20%. IRO was present in regions such as Dobruja and Edirne because Bulgarian officers were well organized and trained by Russians, while Turks were a bunch of villagers.
Also, just to prove what I had stated:

And let's look at the newly coming Proto-Bulgar article by Stamov that PAGANE mentions:
1- What is "a distinct Caucasus signal?" He uses Vahaduo(this is also funny btw) to make such conclusions, what did he see? 10 Distance to Alans or something?
2- How Proto-Bulgarians can be close to the THRACIANS?
3- How you concluded they are Sarmatians?
Well, it is Q-L330, which is Hunnic.
The Alan L330 which I posted before in this forum was an outlier, and his admixture was actually Bashkir-like. So, it has nothing to do with Sarmatians or actual Alans.
Interesting... Claiming Eastern Roman heritage up to 30%, yet 0-10% Thracian at the same time. That's probably because he considered Scythian Moldovans as Proto-Bulgars, while they are Thracians.
I mean, me, being all of my ancestors are from Thrace, have only 0-10% Thracian?

So yes, what we see here is this research was done by someone who is highly biased or not qualified enough to carry out it. In this sense, it is also wrong to expect that this article will make a contribution to what we know. Perhaps it can work if he decides to share all the data publicly yet what he will write in the article already will manipulate people.
