Lol so a person from DNA.Land emailed me. Source files?
Thank you so much for taking part in DNA.Land!
Our “Sardinian” cluster is made up of source files from Sardinia. That being said, until very recently we grouped together all Ancestral Cluster percentages below 5% in a user’s Ancestry Report. That change was made in the most recent version of the report to give users as much information as possible.
Think of your genome as a beam of light. The reference panel of each service’s algorithm acts as a prism that decomposes this beam of light to its potential components. Since each prism has different physical properties, the rainbows they produce will all be at least a little bit different.
As each reference panel has its own strengths and caveats, it is best to observe your genomes through as many prisms as you can. Only in this way can you better illuminate your past.
DNA.Land is very inaccurate.
As someone who has tested himself and his family with many different tools and companies, I could easily say that DNA.Land's results are one of the least reliables.
I wouldn't take what they say seriously, if you are having the test for identity issues, and not just for fun or curiosity.

Also, I find it hard to believe that Poles would be waving German flags around, as the Poles have a great dislike for Germany.
"Finnish" could easily show up in East Prussian Germans for sure.
