An SU(3) fit can account for the relative magnitudes of the amplitudes for the decays and , but neither the current BaBar sample (based on an integrated luminosity of 22 fb?1) nor the CLEO analysis has significant evidence for the decays and . At this level one is unable to compare magnitudes and phases with theoretical predictions. The purpose of this Letter is to advocate an analysis using the full BaBar sample (more than 20 times the 2002 value). It should definitively determine whether predicted magnitudes and phases agree with experiment. A similar analysis should be possible with an even larger sample of events collected by the Belle Collaboration at KEK-B.
