Notes. Computations were performed for the third full cycle during the He-rich accretion phase ($M_{\mathrm{WD}}^{\mathrm{init}}$ = 0.7303 M_⊙ – see Table 2). For the sake of comparison, we also report data for the standard case. The accreted mass ΔM_acc, the mass of the He-rich zone with X(⁴He) > 0.1 $\mathrm{\Delta }{M}_{\mathrm{He}}^{\mathrm{pk}}$, and the mass lost during the flash-driven RLOF ΔM_lost are in 10⁻² M_⊙; the WD final mass after the RLOF episode $M_{\mathrm{WD}}^{\mathrm{fin}}$ is in M_⊙; the ignition density for He burning ρ_He is in 10⁵ g cm⁻³; the maximum temperature attained during the He-flash $T_{\mathrm{He}}^{\mathit{max}}$ is in 10⁸ K; the maximum luminosity during the He-flash $L_{\mathrm{He}}^{\mathit{max}}$ is in 10¹² L_⊙; and the retention efficiency $\eta =1-\frac{\mathrm{\Delta }{M}_{\mathrm{lost}}}{\mathrm{\Delta }{M}_{\mathrm{acc}}}$.
