HEAD TO HEAD
Barbados vs Guyana
Verdict
Guyana holds a 79–21 advantage over Barbados on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (77% of the combined total, $24.7bn) and logistics & power projection (88% of the combined total, 7).
2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
