Davidski has launched his own K=10 admixtures using the Dodecad Calculator script.
Whereas Dienekes had a Northwest and a Northeast European component, Davidski opted for a West + Southwest and North + East ones, giving the cline a different orientation. At first sight, his Mediterranean and West Asian admixture look similar to the ones used by Dienekes.
I had a quick look at the data.
The North + East European admixture obviously peaks in the Lithuanians, Russians, Belarusians and Poles.
The Spaniards range from 16% to 30%, the French from 29 to 42%, and the Germans are from 40 to 57%, probably in a clear Southwest to Northeast gradient.
It's interesting that the South English (Kent and Cornwall) have between 40 and 47%, the Dutch between 36% and 50%, the Danes just around 50% (48 to 51%), but the Swedes and Norwegians are always above 50% and up to 65% for the Swedes. This clearly sets the Norwegians and Swedes apart from other Germanic people.
The West + Southwest European component does not have quite the inverse gradient as the North + East one. It has a similar frequency among the Swedes (29-45%), Danes (29-45%), Norwegians (38-45%) and Germans (31-45%), but is clearly higher in the Dutch (41-50%) and English (45-54%). The English range is actually very close to the French (44-55%, or 61% if the Basques are included), North Italian (46-55%) and even Spanish one (50-55%, or up to 71% if Basques included).
I think this West + Southwest European admixture correlates better with R1b than Dienekes' West European admixture.
The West Asian element is actually quite Caucasian. It confirms a hotspot around the Netherlands (4.5% to 11.5%) and Germany (up to 14%), which I assume to be related to the Neolithic farmers from the Caucasus (LBK culture). The Kentish and Cornish have respectively up to 8 and 9% of West Asian. Scandinavians never exceed 3% though, and typically have 0%. This means that the Caucasian Neolithic farmers didn't reach Scandinavia.
The Greeks (22-37%) and Italians (8-15% in the North, 13-32% in the South) obviously have far more West Asian than anybody else in Europe, which corresponds to their much higher percentages of hg G2a, J1 and J2.
The Russians and Ukrainians can have up to 11% - probably the North Caucasian influence.
The Mediterranean admixture also peaks in Southwest Asia (Bedouins, Saudi, Yemeni, Jordanians, Palestinians, Jews, Syrians), as well as in North Africa (28-35%).
In Europe, the highest frequency is found in the Greeks (18-29%) and South Italians (14-29%), then in the North Italians (10-16%), Spaniards (4-17%) and Portuguese (10-14%). In Western Europe, this admixture gradually decreases when moving north. The French have from 0% to 12%, the Germans from 0 to 6%, the Dutch/English from 0% to 4%, the Danes/Swedes 0 to 3%.
Interestingly, the Slavs have quite a lot of Mediterranean, more than with the combined Mediterranean and Southwest Asian in the Dodecad. Russians have from 3 to 11%, Poles from 6.5% to 12%, Ukrainians from 8 to 14.5%, and Bulgarians from 15 to 20%.
Like for the Dodecad, I believe that there is a strong E1b1b and T (and perhaps I2a) correlation with this admixture, although in this case there is also a significant influence of J1c3 lineages.
