Nigeria holds a 97–3 advantage over Sao Tome and Principe on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (100% of the combined total, $252bn) and active personnel (99% of the combined total, 143.0k).
2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
