Fiji holds a 78–22 advantage over Tonga on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (91% of the combined total, $6.0bn) and active personnel (80% of the combined total, 4.0k).
2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
