The age conjecture for counting G-fields

Let $K$ be a number field, let $G$ be a finite group, and let $V$ be a finite-dimensional faithful representation of $G$ over $K$. Let $N_{G,V,K}(B)$ count isomorphism classes of $G$-fields $L/K$ with $V$-discriminant $D_L^V\le B$. Let $\operatorname{age}(G)$ be the minimum of the age function on $G\setminus\{1\}$, and let $\upsilon(G)$ be the number of nontrivial $K$-conjugacy classes with minimum age. The age conjecture. If $K$ is sufficiently large, then

$$N_{G,V,K}(B)\sim CB^{1/\operatorname{age}(G)}(\log B)^{\upsilon(G)}.$$

This is proposed as a representation-theoretic analogue of Malle's conjecture, with age replacing index; the source gives no resolution status.
