Yeah for that, they make a good job, with nice and useful informations etc, but concerning the point of their coordinates they have the same format than G25, but they are not G25 properly. As example with their coords, I tend to be a little more southern shifted with less northern euro admixture, and more Miiddle Eastern shifted but in other hand less "african shifted" (well in fact I aim especially the north african here). In comparison in this view with the G25 coords my results with coords from DNA Genics seem more weirds.
Globally on a PCA it's not the same but it's near, it's close.
We therefore unfortunately cannot make a real comparison, at least in a serious way, with the G25 coordinates that we have and use with the data sheets that we have from Davidski.
It would be nice if they also offered their own datasheet based on the method they use to produce their coordinates in the G25 format

My previous results was with Ancestry's data, now with Ancestry I have no matches and yeah I think that makes more sense for me....
They updated the results:

Scientific Details
Algorithm version: 2.4 - April 2024
Reference dataset updated: March 2024
The human population is a complex and branching network of interconnected lineages that started in Africa where they diverged, branched out, and spread across the world. Rather than a simple, direct line of ancestors, it involves numerous branches, splits, and intermixing between different groups of people throughout history. This complexity arises from factors like migration, interbreeding, and the constant diversification of human populations over time. As a result, tracing one's ancestry back in a straight, linear manner becomes increasingly challenging as we go further back in time due to the intricate web of connections among individuals and groups.

Shared Roots Matches report aims to identify small segments of your DNA by comparing each segment with the DNA from ancient samples. The goal is to find the closest and most accurate match possible. To ensure the validity of these matches, specific criteria are employed, which are elaborated upon below.

How does this analysis work?
The comparison analysis of any of these samples with your genome utilizes an Identity-by-State (IBS) approach. This method is particularly effective when dealing with ancient DNA samples, where traditional DNA matching segment analysis methods may not be applicable due to the antiquity. By analyzing small segments that are relevant and genetically unique, the IBS approach allows us to identify shared genetic segments more accurately.
However, it's important to bear in mind that genetic analysis is a field of science that is continually advancing. The current results represent the best outcome achievable with our current knowledge. As the science continues to evolve, some of these results may change, potentially leading to improvements in the accuracy and understanding of the results.

Our algorithm considers multiple factors to determine your connection to this sample:

The number of Single Nucleotide Polymorphisms (SNPs) present in the DNA segment.
The chromosome region in which the segment is located.
The distance between the first and last position of each segment.
The frequency of the segment among the worldwide population, compared to its frequency among populations with similar ancestry of this sample.
The Match Quality Score
The match quality score is a measure of the reliability of the analysis. It is calculated by taking into account the number of SNPs, the length of the segment, and the frequency of the segment among the worldwide population, compared to its frequency among populations with similar ancestry of this sample.

How the quantity of SNPs in the RAW file influences the matching
Depending on the raw data file of your sample, it is possible that your raw file may contain more SNPs per centimorgan. Consequently, the number of shared SNPs may be greater compared to another raw file that matches the same segments.

References
The analysis method employed in this report is well-established within the scientific community. For your reference, we have adopted a similar approach in this analysis to that described in the following scientific papers:

Is this really reliable ? It's seems unlikely to me that I could match such samples.

Dna genics says :
"it does not imply that this sample is your direct ancestor; it simply indicates that both you and this sample share a small piece of DNA that could be related to a common ancestor thousand of years ago."

How I could have a common ancestor, even in the last thousand of years, with people from such geographical distance ?
It would be plausible to me that I can have a match at about 4-6 centimorgans with any European medieval individual from Spain to Belarussia... but ancient Oceanians really ?

https://www.nature.com/articles/s41598-020-64007-2
"Generally, European IBD blocks longer than 4 cM derive from common ancestors living 500–1500 years ago or even more recently11, which is a period roughly contemporaneous to our Medieval individual. The network based on >6 cM genomic blocks in modern Europeans uncovers some interesting genealogical features that are not evident in the commonly applied population genetic methods such as PCAs or ADMIXTURE analyses.

It could indicate ancient East or South Asian ancestry- not entirely out of the realm of possibility given the Huns and other Steppe populations crossing into Europe.
As an example: I often get tiny amounts of Oceanian/Aboriginal/Andamanese on G25 runs. In my case, I know this to be most likely a signal of an Austronesian population like the Santali who contributed to the Romani gene pool. You're half-Serbian so more likely to have Hungarian ancestors in genetic time, potentially with not insignificant East Asian admix. In my case, you have to go back to the thirteenth century to find a Hungarian ancestor. Despite this ancestor being significantly East Asian admixed (her mother being of the Cumans), I score next to no East Asian on calculators.

Anyway, they updated the algorithm and added new populations. I don't match with as many as I do on the Ancient African Shared Roots, which is surprising:
