Translated V-strict promotion order conjecture

Let $V=\{a,b,c\}$ be the three-element poset with $a\lessdot b$ and $a\lessdot c$, let $\mathcal{L}_{V\times[\ell]}(R^q)$ denote the set of $V$-strict labelings with restriction function $R^q$, and let $\operatorname*{Pro}$ denote promotion. Translated V-strict promotion order conjecture. Promotion on $\mathcal{L}_{V\times[\ell]}(R^q)$ has order dividing

$$2q.$$

This is presented as equivalent to the V-poset rowmotion conjecture; computational evidence and a reflection interpretation support it, but it remains unproved.
