Zambia holds a 67–33 advantage over Malawi on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (71% of the combined total, $406m) and economic size (GDP) (69% of the combined total, $25.3bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
