My closest match from Flashball's collection of results is a northern French from Picardy with a bit of Belgian:


Target: French:KatPère(85%Picardie+10%Flemish+5%Anjou)
Distance: 0.7401% / 0.00740145 | R5P
30.2 Frisians
26.0 Gallia_Belgica
17.2 Balto_Slavs

11.8 Vandals


Here is a another one from the extreme south:

Target: French:SouthEasternFrance(94%04BassesAlpes6%Gard)
Distance: 0.4675% / 0.00467524 | R5P
36.0 Aquitania
25.6 Italia_North
20.2 Goths_Gepids
11.6 Balto_Slavs
6.6 Greece


It is factually wrong to say people who score significant Balto Slavs must have recent eastern Euro. These people have none and they have much better distance than me on this calculator (not sim). I should probably even score a little more due to my 25% German + 25% Belgian but G25 is not anywhere close to be that precise or reliable from one admix dataset to another. I am no more Breton and Aquitanian than anything else, nor these people are part Frisian or Greeks (i was getting Frisian and Thracian too before adding Armorica). Admixes can get very random unless we are talking about specific non Euro ancestry. Single distances are more important, always.


This is my best matches on Flashball collection (better single distances):

I have also thought the same as you, that unique distances are more important and even then they are unrealistic (for example, if you mix a Mediterranean with a Dinarid and an Alpine enough, the program will probably classify you as northern Italy, even if you don't actually come from that region).
The G25 conjectures are so crazy that after adding the Alans, I am now much more Thracian and Illyrian than before...
I think that this tool should be greatly improved, or at least add ALL THE MIGRATION GROUPS OF HUMANITY, to increase the database with which to compare the samples. Although it is true, I find the work commendable.

This is all derived from nMonte, an algo designed for Casinos, hence the name "n Monte-Carlo". You can't conclude too much based on it, just a general pattern. People who try to read too much into it clearly have no business tampering with calculators. False premises lead to false conclusions. The most reliable conclusion is the single pop distances. Even then a particular dataset can skew perceptions if you are closer to a specific region that isn't sampled, thus showing your best match in another country.

As you have just witnessed yourself, adding ONE SINGLE sample you can change the populations that show up in the admix, since the algo might have to rebalance everything even using completely different populations just to get the absolute best fit he can trading more often than not distance for realism (that's the main culprit of the algo). Contrary to what people think, a great distance is rarely a good sign. Similar thing happens when using ADC, population mixes can change entirely.

Completely agree with you.
Or as they say, the dream of reasoning produces monsters.
Sometimes it is necessary to use common sense, an AI will never be able to discern the particularities of each sample... that is why there are still some Basques who believe they are Georgians... although all Europeans are Georgians to a certain extent, that does not make us unfailingly Georgian.
