These figur:s 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 .n easions when the daily average power level exceeds the 100'," line (or the restricted power lesel kne). In such c.ises, the average daily unit power output sheet should be footnoted to explain the apparent anomaly.
