For illustration, we assume a hierarchy, $\\sim 1: \\lambda : \\lambda^2$ ($\\lambda=0.2$), between a dominant $\\Delta S=1$ penguin amplitude, a NP amplitude and a Standard Model amplitude with weak phase $\\gamma$. An uncertainty from SU(3) breaking corrections, reduced by using ratios of hadronic amplitudes, is further suppressed by a factor $\\lambda$.
