Family finder is commercial bs.
The best autosomal calculator is Eurogenes K13..
Who have told you this? Its not true. Have you done autosomal test? Family Finder is just one of tests offered by FTDNA. Family Finder then branches out into Matches, Chromosome Browser, Linked Relationships, myOrigins, ancientOrigins, and Wellness Report categories. Family finder also includes a labaratory DNA testing of your sample and provides you with raw data. What you wanted to say is probably about myOrigins category under Family Finder test. Its true that myOrigins is just a calculator, but with all due respect, out of all actual testing companies FTDNAs myOrigin is for sure most precize and well updated calculator. Currently myOrigin is very precize regarding Balkans and i would for sure take it into consideration.
The Eurogenes K13 is only one of free calculators offered by Gedmatch (free open data personal genomics database). Not an actual testing company. You can upload your raw data from Family Finder into Gedmatch to see how other calculators react on your raw data. There is plenty of useful and good calculators offered by Gedmatch and not only K13. There is newer calculator under Eurogenes project Eurogenes EUtest V2 K15. Then there are K9, K12, K36.
Also try MDLP K16 Modern, MDLP K23b, puntDNAL K10 Ancient, puntDNAL K12 Modern, puntDNAL K13 Global, puntDNAL K15, Ancient Eurasia K6, Gedrosia K3.
I have already run all these calculators and Albanians have actually mapped themselves long ago on K15 DNA map.
Also i would suggest uploading raw data to DNA Land as they also offer very interesting calculation for free. And dont only look at components that Gedmatch calculators displays but also look at population similarities and genetic distance from various populations.
It is important to understand difference between testing company and various calculators that work based on raw data produced by testing laboratories.
Gedmatch K13 is for sure good calculator but far away from being perfect or best. All of calculators work based on similarity and when realistically looking at all these calculators FTDNAs myOrigin is without doubt one of most accurate calculators out there. Then of course for more advance approach or some precise targeted area its good to run specific Gedmatch calculators.
