Because the LoFi data barely guide the MuFi results, the overall prediction highly depends on the position of the HiFi calculations. Between 0.0 and 0.5 (corresponding to -180 • and 0 • ), the data points lead to a good approximation of the HiFi data based on five samples. Between 0.5 and 1.0 (corresponding to 0 • and 180 • ) the same number of samples does not lead to a reasonable qualitative prediction because the MuFi mean values miss the local minimum near 0.75 (i.e. 90 • ). Nevertheless, the MuFi approach correctly predicts, besides identifying the LoFi method being a bad prior, the maximum uncertainty near 0.75 and thereby helps to detect the so-far overlooked minimum in the HiFi curve.
