Croatia holds a 67–33 advantage over Slovenia on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (63% of the combined total, $2.1bn) and logistics & power projection (81% of the combined total, 25).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
