Abstract: This note presents hadronic FEI performance plots associated with the analysis work presented in BELLE2-NOTE-PH-2019-031 for approval made using proc 10 and bucket 8 data (8.7 fb$^{-1}$) of early phase III data. Plots include a comparison of the classifier output for the tag-side B mesons in data to the shape expected from simulation, fits to the beam constrained mass distributions in data in different purity regions, the beam constrained mass distributions of neutral and charged tag-side $B$ mesons in data with different categories of tag-side $B$ meson decay modes stacked and, finally, fits are shown to the lepton momentum in the signal $B$ rest frame for a reconstructed signal side $B \rightarrow X \ell \nu$
