Methods based on charge-conjugation and isospin symmetries involve very little theoretical uncertainties, while schemes based on flavor SU(3) involve uncertainties due to SU(3) breaking. Resolving these uncertainties requires further studies involving a dialogue between theory and experiments.minor corrections, several references added and updatedHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
