Cuba holds a 66–34 advantage over Jamaica on the Relative Advantage Index, a clear margin.
The margin is driven by economic size (GDP) (83% of the combined total, $107bn) and active personnel (89% of the combined total, 49.0k). Jamaica leads on military spending.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
