Mixed-volume asymptotic conjecture for amoeba contours

Let Vd={f1,d==fr,d=0}(C)nV_d=\{f_{1,d}=\cdots=f_{r,d}=0\}\subset(\mathbb C^\ast)^n be the complete intersection under consideration, and let Δi,d\Delta_{i,d} be the Newton polytope of fi,df_{i,d}. Set k=nrk=n-r, and let Θ1,d,,Θk,d\Theta_{1,d},\ldots,\Theta_{k,d} be the Newton polytopes associated with the logarithmic Plücker coordinates. Write MVMV for the corresponding mixed volume. Mixed-volume asymptotic conjecture. The contour degree satisfies

Rdeg(CAVd)=O(MV(Δ1,d,,Δr,d,Θ1,d,,Θk,d)).\mathbb R\deg(\mathcal C\mathscr A_{V_d})=O\left(MV(\Delta_{1,d},\dots,\Delta_{r,d},\Theta_{1,d},\dots,\Theta_{k,d})\right).

This refines the degree-growth prediction by expressing the bound in toric terms. Bernstein-type reasoning and the support containment of logarithmic derivatives provide evidence, but the supplied text does not state a resolution; the conjecture remains open.
