Left: Runtime-to-MSE comparison for the filtering problem in Sect. 6.2 using the fully-discrete numerical method. Right: Graph of \((\text {Runtime(MLEnKF)}, \, \text {MSE(MLEnKF)}\times \text {Runtime(MLEnKF)}/L^3)\) for the fully-discrete numerical method. Note the y-axis here, and in future such plots, has linear scaling
