A supply chаin strаtegist trаcks the histоrical mоnthly perfоrmance of a product line and logs the following metrics for a given period: Demand D_t = 300, Forecast F_t = 285. For the subsequent period, demand reaches D_t+1 = 270 while the forecast is set at F_t+1 = 290. Compute the net Mean Absolute Deviation (MAD) across these two discrete data blocks.
