Senegal holds a 91–9 advantage over Gambia on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (97% of the combined total, $567m) and economic size (GDP) (93% of the combined total, $32.8bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
