VMI delta calculations

There are multiple operation formulas for the vmi delta calculations. Lets compare using the example graph below

In the graph you can see there are 2 trend within the configured measurements range of the aggregate. Lets suppose the following; Trend 1 5 hours long 10 delta -> change per hour is 10 / 5 = 2 per hour Trend 2 1 hour long 1 change -> change per hour is 1 / 1 = 1 per hour As you can see there there is quite the difference in change per hour between the last two trends, and the operation formulas use these changes per hour in different ways.

Option: "Average of the delta of each trend (middle gound between responsive and smoothing", "lastTrendDelta" Will take the average of the trends in the measurements window leading to (2+1)/2=1.5 change per hour as final output Option "Takes the last trends delta (most reponsive)" will just look at the last found trend leading therefor to 2 change per hour Option "Average of trends weighted by their length (most smoothing)" will weigh the change per hour based on the the length of each trend period leading to the following calculation; (( 5*2 + 1*1) / 6) = 1,83
