The volume bound after augmentation of an alternating link

Let $K$ be a hyperbolic alternating link, and let $B$ be an augmented unknot around any two parallel strands of $K$. Augmentation volume conjecture.

$$\operatorname{vol}(K) < \operatorname{vol}(K\cup B) \leq 2\pi\log\det(K).$$

This conjecture would give an upper bound on the volume change caused by drilling out an augmented unknot. The source states that it follows from the Vol-Det conjecture and presents it as a new bound whose general validity remains open.
