Simulation results for Investigation 2 for a system with λ₁ = 6.0, λ₂ = 5.0. (Upper) The top-down bias ${\lambda }_2^H$ = 0. (Lower) The top-down bias ${\lambda }_2^H$ = ${\lambda }_2^{H,cr}$ = 0.775. ${\lambda }_2^H$ = ${\lambda }_2^{H,cr}$ is the value derived in the analysis for the top-down bias to just produce equal rates in H₁ and H₂, overcoming the difference between the bottom-up inputs shown as λ₁ and λ₂.
