B}(J/\psi \to \rho \pi)$ is $(1.27 \pm 0.09)\%$. Since about 1/3 of $J/\psi$ decays can be ascribed to non-$3 g$ mechanisms, we expect $\rho \pi$ to account for about 2% of all [*hadronic*]{} $J/\psi$ decays, and thus no more than this percentage of $\ppp$ hadronic charmless decays. (The availability of more final states undoubtedly reduces the $\rho \pi$ fraction in comparison with $J/\psi$ hadronic decays.) We thus estimate for hadronic charmless decays ${\cal B}(\ppp) \gsim 2 \times
10^{-4} /2\% \simeq 1\%$, again give or take a factor of 2 depending on the sign of $\phi$. This is consistent with our previous estimate.

It is even possible that we have seriously underestimated the role of non-charmed final states in hadronic $\ppp$ decays. If so, there is a chance of reconciling the smaller cross section for $e^+ e^- \to \ppp$ measured by the Mark III Collaboration using a comparison of single-charm and double-charm production, $\sigma(\ppp) = 5.0 \pm 0.5$ nb [@MkIII], with higher values obtained by other groups using direct measurement [@LGW; @XB; @MkII; @BES], whose average I find to be $8.0 \pm 0.7$ nb.[^7] This possible discrepancy was a factor motivating the studies in Refs. [@Zhu; @Walid].
