Impact \(\chi _s\) for best-case scheduling, an MDA preceding an IRS campaign by the prophylactic period \(2g^{-1}\), for different transmission intensities. In both simulation and the Ross–Macdonald variant, the impact of the interventions grows for small \(R_0\), generally increasing to, or exceeding twice the impact of isolated campaigns. Interestingly, while the Ross–Macdonald model is monotonic, with growing impact for higher transmission intensities, openmalaria obtains a maximal impact and slowly wanes. Simulation data is plotted in blue (stochastic noise is apparent) and the grey highlighted background is drawn only to guide the eye; it has no numeric merit
