Variation in ⁷Li-abundance in average values (black squares) with our models of various overshooting efficiencies at the early evolution. The applied values of ${\mathrm{\Lambda }}_{\mathrm{e}}^{\mathrm{p}}$ and initial A(Li⁷) are indicated in the label. The two panels on the right-hand side focus on the plateau (top-panel) and the RGB bump region (bottom-panel), with the re-derived 3D+NLTE data being shown in grey dots. The shaded area marks the uncertainty coming from the primordial lithium, $\mathrm{A}{(}^7\mathrm{Li})=2.{69}_{-0.03}^{+0.04}$ of the “growth” model.
