  The new angular analysis of the decay $B \to K^* \ell^+ \ell^-$ recently
presented by the LHCb Collaboration still indicates some tensions with the
Standard Model predictions. There are several ongoing analyses to solve the
problem of separating hadronic and New Physics effects in this decay, but the
significance of the observed tensions in the angular observables in $B \to K^*
\mu^+\mu^-$ is still dependent on a theory guesstimate of the hadronic
contributions to these decays. Using the new data from LHCb we offer two tests
which make a statistical comparison to determine whether the most favoured
explanation of the anomalies is New Physics or underestimated hadronic effects.
We then analyse the usefulness of these tests in two future scenarios. Finally,
we update our global fits to all available $b \to s $ data and discuss the
impact of the new LHCb measurements.
