Calculation of virtual sensors for simple and windowed metrics at the example of magnitude and variance, simulated for two consecutive time-steps. For a window size of $w_{\mathrm{virt}}$, windowed metrics have a delay of $\Delta t=\frac{w_{\mathrm{virt}}-1}{2}$, while simple metrics such as magnitude always have a delay of $\Delta t=0$.
