We show that ΔI=3/2 transitions for quark W-emission K2π diagrams and independently the current algebra-PCAC consistency scheme for all three K2π amplitudes are extremely accurate, within 3% of the data. Although the same analysis applied to D2π decays roughly approximates recent experiments, the agreement is only valid to within 25%–40% of the data.

The observed branching ratio of D°→K+π− to K−π+ is obtained using current algebra-PCAC consistency. The latter approach also sets the scale for the three Cabibbo angle-enhanced [Formula: see text] decays in a manner compatible with data.
