For the image of a uniform cube under a spherical coordinate map, we prove that finite messages from t blocks of $\Theta(d)$ exact Gaussian measurements reveal only $O_A(dt)$ information when each message has at most $\exp(Ad^2)$ values, for fixed A . The same bound holds when each message is supplemented with a nested cell that restores the required geometric spread.
