These ' figures will be used to plot a graph for each reporting month. Note that when maximum dependable capacity is used for the net electrical rating of the unit, there may be occasions when the daily average power ^1evel exceeds the 100% line (or the restricted power level line). In such cases, the' average daily unit power output sheet should be footnoted to explain the apparent anomaly.
