This formula:
1. Searches the _Load channel.
2. Looks for the _Load channel to drop 80% from its peak value. 80% is the value of the input BreakDrop.
If PeakLoad = 100lbs, then the calculation returns the number of the data point when the load has dropped
to 20lbs.
If PeakLoad = 80lbs, then the calculation returns the number of the data point when the load has dropped
to 16lbs.
