Kiribati holds a 81–19 advantage over Tuvalu on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (83% of the combined total, $308m) and logistics & power projection (78% of the combined total, 7).
3 factors — military spending, active personnel, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
