Naive Chudnovsky bound for monomial ideals

Let II be a monomial ideal. Define its initial degree by α(I)\alpha(I), its naive Waldschmidt constant by α~(I)\widetilde{\alpha}(I), and its big-height by

big-height(I)=max{ht(P)PAss(I)}.\operatorname{big-height}(I)=\max\{\operatorname{ht}(P)\mid P\in\operatorname{Ass}(I)\}.

The naive Chudnovsky bound. The naive Waldschmidt constant satisfies

α~(I)α(I)+big-height(I)1big-height(I).\widetilde{\alpha}(I)\geq \left\lfloor \frac{\alpha(I)+\operatorname{big-height}(I)-1}{\operatorname{big-height}(I)}\right\rfloor.

This is proposed as a counterpart to the Chudnovsky bound for the Waldschmidt constant; the supplied source gives no evidence that it has been resolved.
