We find it impossible to reach a satisfactory agreement, the confidence level (CL) of the best fit is smaller than .1 %.\n  The main reason for this failure is the difficulty to accomodate several large experimental branching ratios of the strange channels. Furthermore, experiment was not able to exclude a large direct CP asymmetry in $\\bar {B^0}\\to\\rho^+ \\pi^-$, which is predicted very small by QCD factorisation.
