There has been a recent claim by the LHCb Collaboration that the measured value of $\\Delta A_{\\rm CP}$ shows an uncomfortable tension with the SM prediction, almost at the $8\\sigma$ level. Motivated by this claim, we critically re-examine the data on all the $B\\to \\pi K$ modes, including the CP asymmetries and CP-averaged branching fractions.
