Recent investigations of mantle convection with mobile plates have documented a mode of convection with periodic and/or aperiodic plate reversals (2-D) or reorganizations (3-D). We show that it is possible to calibrate plate formulations so that three different modeling methods reproduce the global flow diagnostics to within 3%. In 2-D calculations, plate reversals are independent of the method of plate generation once the calculations are tuned to reproduce the same physical characteristics (e.g., Nusselt number and plate velocity). The periods of oscillation of the flow reversals from three different plate methods agree to within 4%.
