Senegal holds a 65–35 advantage over Mauritania on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (64% of the combined total, $567m) and economic size (GDP) (75% of the combined total, $32.8bn). Mauritania leads on active personnel.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
