Genus formula conjecture for lens space knots in \Sigma$2,3,7$

Let $K_{p',k}$ be any knot whose parameter $(p',k)$ occurs in the displayed table for lens space surgeries in $\Sigma(2,3,7)$, and let $g'$ be the table's value in its $g'$ column. Genus formula conjecture. Its genus satisfies

$$g(K_{p',k})=\frac{g'+p'+1}{2}.$$

The table supplies examples of lens space knots in $\Sigma(2,3,7)$, and the conjecture predicts their genera from the tabulated data; the source does not state a resolution.
