Stronger variable reduction conjecture for monomial ideals with linear quotients

Let KK be a field, let S=K[x1,x2,,xn]S=K[x_1,x_2,\ldots,x_n], let ISI\subset S be a proper monomial ideal with linear quotients, and write [n]=1,,n[n]=\\{1,\ldots,n\\}. The stronger variable reduction conjecture. There exists i[n]i\in[n] such that

depth(S/(I,xi))depth(S/I)\operatorname{depth}(S/(I,x_i))\geq\operatorname{depth}(S/I)

and

sdepth(S/(I,xi))sdepth(S/I).\operatorname{sdepth}(S/(I,x_i))\leq\operatorname{sdepth}(S/I).

This strengthens the preceding depth-preserving variable conjecture by adding a Stanley-depth inequality; the source gives no resolution.
