Degeneration conjecture for isolated A1 singularities

Let $R_{\mathbf{v}}(t)$ be a contribution to the zeta function associated with a monomial class $\mathbf{v}$, and let $\operatorname{deg}(R_{\mathbf{v}})$ denote its rational-function degree. An isolated $A_1$ singularity is an ordinary double point, also called a conifold point. Isolated-$A_1$ degeneration conjecture. At an isolated $A_1$ singularity, the degree of every contribution decreases by exactly $1$. The source provides computational evidence through the displayed degeneration table, but no resolution status.
