Issues with "k13 updated spreadsheet"

[SouthDutch7991]

This one is way less accurate for me, am I the only one? This is from the original, and a decent estimate of what I know about my ancestry. As from paper it should be ~80% English from the west country and ~20% east and southeast Germans:

Target: SouthANCESTRYk13
Distance: 1.2989% / 1.29890243 | ADC: 0.25x RC
64.9 Southwest_English
22.2 East_German
11.6 Southwest_French
1.3 Yoruban

Yet the updated never even approaches something accurate:

Target: SouthANCESTRYk13
Distance: 2.2445% / 2.24451146 | ADC: 0.5x RC
59.5 French_Northwest
35.1 Dutch_South
4.5 Southwest_French
0.9 Yoruban

Removing northern French samples improves it but still leaves it in a weird spot:

Target: SouthANCESTRYk13
Distance: 1.2587% / 1.25872810 | ADC: 0.25x RC
76.8 English_Southwest
15.0 Southwest_French
7.1 Polish_Lower_Silesia
1.1 Yoruban

Without any French:

Target: SouthANCESTRYk13
Distance: 1.5137% / 1.51370894 | ADC: 0.25x RC
77.2 English_Southwest
14.2 Spanish_Cantabria
7.6 Polish_Lower_Silesia
1.0 Yoruban

Why? I've found the new spreadsheet just doesn't work at all for any of my family members and makes no sense. I have little or no known southern European ancestry.

Many people's scores don't match their ancestry, it's not unusual, especially when you have populations that are close like NW Europeans. The calculators are not guaranteed to be accurate for individuals. What do you get in in k15 updated/Dodecad K12 updated/Lucas's K36 report or G25?

Plus I'm not sure the French Northwest average is that accurate, but I can't prove it. You're probably closest to Dutch_South in reality.

the southwest french then should be included with the English admixture. its probably taking the neolithic anatolian admixture(sardinian-like) and mixing it with some of the celtic to show southwest french or iberian. because Iberian, basque, and southern french populations can be broken down to around 50% celtic and 50% Neolithic anatolian.
