The graph below demonstrates the differences between the instantaneous, the instantaneousToMean and the MeanToMean methods when aggregating data.
The blue line (first column in the table) shows the original 15 minute data. The red line (second column) is the result of the instantaneous disaggregation. The next two columns show the results of the meanToMean (light green line) and the instantaneousToMean (dark green line ) method.
