Most decay modes (other than the semileptonic modes) that involve a neutral ${{\mathit K}}$ meson are now given as ${{\mathit K}_S^0}$ modes, not as ${{\overline{\mathit K}}^{0}}$ modes. Nearly always it is a ${{\mathit K}_S^0}$ that is measured, and interference between Cabibbo-allowed and doubly Cabibbo-suppressed modes can invalidate the assumption that 2$~\Gamma ({{\mathit K}_S^0}$ ) = $\Gamma ({{\overline{\mathit K}}^{0}}$).
