Peru holds a 62–38 advantage over Ecuador on the Relative Advantage Index, a clear margin.
The margin is driven by economic size (GDP) (70% of the combined total, $289bn) and logistics & power projection (71% of the combined total, 48). Ecuador 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
