Iran holds a 78–22 advantage over Azerbaijan on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (86% of the combined total, $475bn) and military spending (60% of the combined total, $7.4bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
