Fwiw, Dutch world chess champ Euwe set Q=R+B+P=10 with R=5.5 and B=3.5. Chess players have argued whether N is microscopically less than a single B (usually saying yes). In any case, if N=3.5, 2N+B=10.5 (more than a Q - Euwe argued in an old middlegame book with Kramer that 3 pieces are usually slightly better than a Q).
I had a chess master friend that once told me that when Q is vs. 'other material', it was usually critical whether the 'other material' side had 'stickiness', that is that its pieces stuck together and defended each other effectively.
