I'm new here and I have no clues! Please help me! Why are 1, 2, 3 and 4 population approximation so different? Approximation starting with 9.2, how far is that? Thank you!

If you imagine a 2D map of the world where these populations are placed, you are plotted on that map with a "pull" towards where these populations are placed, which in this case indicates southern European ancestry. You may not have ancestry from any of these groups, as they are just points on the map that are used to plot your own ancestral mix. 9 is fairly high by European standards, which indicate that you are likely quite mixed, or they lack a good reference sample that might reflect your ancestral build up correctly..
