The values in the original PDF don't really add up [1]. It doesn't really change much, but it's still weird. If you apply the formula in the PDF to the listed values, they're all 1-5 points off:

    Each country’s value in each category is given the indicated
    weighting to achieve a country’s total score using the formula
    ((Visa Free Travel x 0.5) +
     (Taxation x 0.3) + 
     (Perception x 0.1) + 
     (Dual Citizenship x 0.1) + 
     (Overall Freedom x 0.1)).
