The Slavs that settled in southern Albania from around 600 AD were undifferentiated or 'generic' Slavs, not 'Bulgarians'. Bulgaria as a political entity later encorporated the Slavicized southern Albania. So southern Albania was no more 'Bulgarian' then the territory of modern Serbia was up to Belgrade under the Bulgars. That being said the population of southern Albania prior to Albanian migrations from the north would have been similar to the native-Slavic mixture in Macedonia, southern Epirus etc. I believe the historical record shows that Albanian migrants cleansed a good part of the area of its inhabitants, toponyms remained.
I don't think Slavic ydna is more then than 20 percent, maximimum 25, of southern Albanians, and I think that is VERY generous. If there is indeed that much or more Slavic blood in Tosks then they would also have to be mixed with other groups that would plot a lot more south than Ghegs on their own. Only that would explain where Tosks do plot, but I don't think thats the case given what is known about Bulgarians/Macedonians. It's just unrealistic to say that without Slavic admixture the Tosks would plot a lot more south than they do now. The people in southern Albania before the Slavs showed up were not from Crete or Cyprus.
Genetic ydna studies are likely to produce a good amount of error vs what they are trying to represent. It's like when they test a whole bunch of people from one village or clan that have the same origin. There has to be some ethnographic discernment in these studies for them to relect the real situation. Right now the only group competent enough to give an accurate assessment of the geneto-ethnic situation of the Albanians are the few mods over at the Albanian Bloodlines project at ftdna.
