I get what you are saying, and I don't have a good answer. But they never consider less than 1/6th.....If you found that you are up to 1/6 jewish by blood, then you can visit Jerusalem for free to learn about your heritage and you may choose to stay there and will be considered a resident from the moment you come into the country.
