If you don’t have an American accent, then why do you expect that a test of which American accent you have is going to produce a sensible result?

I don't expect a sensible result, I just imagined that I would get somewhere either close to the origin of the Americans I know personally, or close to the source of the media I consume (since those are my main connections with the English language), so I'm wondering why my pronunciation is closer to that area in particular instead.

Presumably they wanted to see if they had picked up any accent from their American girlfriend.
