I expected Scandinavian and didn't get a single lutefisk-scented drop. I did get surprised with Finnish/Volga-Ural, though. (British Isles was expected, so I don't know if the whopping 75% I got is related to my Swedes.)
Ancestry does say somewhere in its FAQ that we can expect the BGA to change.
I've just tested with another company that lets you have your raw data, so I plan to send it to Dr. Doug McDonald for analysis. (He's an expert/guru on BGA and kindly does this for free.) His reports are more specific in terms of regions and percentages, but even his numbers/place change over time as more is learned.
I'll be curious to see if anyone replies with unexpected British/no Scandinavian, like you, though. Do you have any Finnish/Volga-Ural?
