The unfounded claims of a too low Standard Model prediction are based on incorrect estimates that neglect the long-distance re-scattering of the final pions in $K\\rightarrow 2\\pi$. In view of the current situation, we have recently updated the Standard Model calculation, including all known short- and long-distance contributions.
