    Experiment with Vahaduo modern scaled Distance Feature

    I was playing with the scaled modern individual version of Vahaduo.

    When I used the distance tab, I noted that I had several Welsh and English individual samples, which is good based on my known ancestry; See my signature for my paper trail percentages.
    but when I run it on the single tab, they aren't there. Instead they've been eclipsed by the Irish, Dutch, Danish, etc samples which aren't very representative of my actual ancestry.

    So I decided to do a little experiment:
    On the Distance tab I set the Max output to 75, copied and pasted the results into a spreadsheet, and repeated process for 100 output.
    In excel I sorted the populations by name

    Of my top 75
    7 Danish
    2 Dutch
    6 English
    5 English Cornwall
    3 French Brittany
    5 Icelandic
    13 Ireland
    2 Norwegian
    5 Orcadian
    13 Scottish
    1 Shetlandic
    1 Swedish
    10 Welsh

    Of my top 100
    12 Danish
    2 Dutch
    10 English
    5 English Cornwall
    5 French Brittany
    1 French Nord
    2 German
    6 Icelandic
    18 Irish
    2 Norwegian
    6 Orcadian
    15 Scottish
    2 Shetlandic
    3 Swedish
    11 Welsh

    Using excel (copy/paste/sort) I figured out how many total samples there were for each of these populations, and calculated what percentage of the total I had for my cloest 75 and 100 samples

    The results: Percentage of total samples in my top 75 closest individual samples
    50% of Welsh (10 of 20 Welsh samples in my top 75)
    50% of Orcadian
    46.4% of Scottish
    41.7% of Icelandic
    38.5% of Cornwall
    33.3% Shetlandic
    31.6% of English
    28.6% of Norwegian
    15.9% Danish
    15.3% of Irish
    14.3% of Swedish
    7.5% of French Brittany
    3.1% of Dutch

    For my top 100 closest on the Distance tab
    66.7% of the Shetlandic (2 out of 3 total)
    60% of the Orcadian (6 of 10)
    55% of the Welsh (11 of 20)
    53.6% of the Scottish (15 of 28)
    52.6% of the English (10 of 19)
    50% of Icelandic (6 of 12)
    38.5% of English Cornwall (5 of 13)
    28.6% of Norwegian (2 of 7)
    27.3% of Danish (12 of 44)
    21.2% of Irish (18 of 85)
    14.3% of Swedish (3 of 21)
    12.5% of French Brittany (5 of 40)
    3% of French Nord (1 of 33)
    3.1% of Dutch (2 of 64)
    2.5% of German (2 of 79)

    Note that similar to my paper ancestry, the English, Scottish, and Welsh have much higher percentages than the Dutch, German, Danish, and Irish who tend to dominate my Single runs on Vahaduo.

    Curious if other members also see results that are also more reflective of their ancestry.
