The comparison obtuse constant conjecture for Alexandrov spaces

From papers

Let MM be a compact Alexandrov space with curvature bounded below, and let ob~(M)\widetilde{\rm ob}(M) be its comparison obtuse constant. Let D(M)D(M) be the double of MM. For a noncompact Alexandrov space MM, let ob~(M)\widetilde{\rm ob}_{\infty}(M) be its comparison obtuse constant from infinity, and let ob(M){\rm ob}_{\infty}(M) be the corresponding obtuse constant from infinity.

Comparison obtuse constant conjecture. The conclusions of the relevant compact results would remain valid with ob~(M)\widetilde{\rm ob}(M) in place of ob(M){\rm ob}(M) when MM is compact. Likewise, the relevant noncompact theorem would remain valid with ob~(M)\widetilde{\rm ob}_{\infty}(M) in place of ob(M){\rm ob}_{\infty}(M) when MM is noncompact.

The conjecture proposes that the comparison versions of the obtuse constants suffice for the paper's compact and noncompact conclusions. The supplied text gives no resolution; the referenced theorem and corollary are not included in the candidate span, so their exact conclusions cannot be reproduced here.
