These fii;ures will be used to plot a graph for each reporting month. Note that by using maximum dependable capacity for the net electrical rating of the unit, there may be occasions when the daily average power level exceeds the I 00% line (or the restricted power level line). In such cases, the average daily unit power output sheet should be footnoted to explain the :ipparcnt anomaly.
