    Así que haciendo una analogía un poco pocha, podríamos decir que soy aproximadamente el resultado de que un marinero irlandés se acostara una noche en el puerto de Olbia con una sarda buenorra estando borracho.(con una sarda que tenía una bisabuela irlandesa algo southern shifted dicho sea de paso, ya que la proporción entre los dos componentes tira más hacia Irlanda).

    Kiss me, because I am Irish (and Sardinian).

    Y aquí se ve perfectamente que estoy a mitad de camino de los dos:

    As I thought you wanted to score in Caucasus, I chose references that could bring out that "component" in Iberians.

    How much of that component do you score in the model without the "East_Mediterranean" reference? Just for curiosity, (it could be the case that you did not score anything).
    Around 12%:

    Target: Gil_Vicente
    Distance: 1.7830% / 0.01782995
    54.0 Atlantic
    21.0 North_Atlantic
    12.6 Caucasus
    12.4 North_African

    Interestingly if i add Cypriots it changes nothing, only if i add something like Greek_Crete:

    Target: Gil_Vicente
    Distance: 1.7799% / 0.01779894
    52.6 Atlantic
    21.0 North_Atlantic
    12.2 North_African
    9.6 Caucasus
    4.4 Greek
    0.2 South_Asian

    55.4 North_Atlantic

    Añadiendo el SSA:

    Target: gixajo_scaled
    Distance: 2.0741% / 0.02074051

    54.8 North_Atlantic
    44.2 West_Mediterranean
    1.0 SubSaharanAfrican

    Añadiendo el NA pero sin SSA:

    Target: gixajo_scaled
    Distance: 1.8604% / 0.01860354

    55.0 North_Atlantic
    39.8 West_Mediterranean
    5.2 North_African

    Con las 4 referencias(North_Atlantic+West_Med+NorthAfrican+S SA):

    Target: gixajo_scaled
    Distance: 1.8604% / 0.01860354

    55.0 North_Atlantic
    39.8 West_Mediterranean
    5.2 North_African

    Sacando medias y redondeando los dos componentes que nos interesan podríamos decir que ando en 55% (55,05%) North Atlantic y 44% (44,1%) West_Med.
    Con Yoruba obtengo un 48% redondeando en ambos.

    Target: Juan_scaled
    Distance: 3.1419% / 0.03141932
    48.2 West_Mediterranean
    47.8 North_Atlantic

    I get this with all 4 samples. Seems that this time the north African "ate" the Yoruba.

    Target: Gil_Vicente
    Distance: 2.2791% / 0.02279072
    56.4 North_Atlantic
    28.8 West_Mediterranean

    Maybe it would be better run it without NA, because NA has also quite West_Med inside. I mean,just North Atlantic+West Med+Yoruba.

    I mean, NA also "eats" the West Med component.

    I guess your West_Med+North Atlantic will be probably around 96% together doing this.

    Yes, more or less:

    Essentially what's happening is that Caucasus and SE European references have significant 'East Mediterranean' ancestry which is basically Iran_N-related ancestry that didn't exist in Western Europe until the arrival of Romans. In K13/15 ADMIXTURE tests that's the East Med, and West Asian to a lesser extent. Neither of the other references have it either, so the model tries to capture it by using Caucasus/Greek/whatever. The rest is more or less overfitting, and scaling producing abnormally high amounts of North African (Pedro Ruben's dad scoring 21% is as hilarious as dumb, as it always happens).
