Query: Testing QCD factorisation and charming penguins in charmless
  ${\boldsymbol{B\to PV}}$   We try a global fit of the experimental branching ratios and CP-asymmetries
of the charmless $B\to PV$ decays according to QCD factorisation. We find it
impossible to reach a satisfactory agreement, the confidence level (CL) of the
best fit is smaller than .1 %.
  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.
Trying a fit with QCD factorisation complemented by a charming-penguin inspired
model we reach a best fit which is not excluded by experiment (CL of about 8 %)
but is not fully convincing.
  These negative results must be tempered by the remark that some of the
experimental data used are recent and might still evolve significantly.
