My observation is that the final simulation run, as shown in result plot, looks like it is only for the last segment of the WFO, instead of the entire desired test period of:

StartDate = 20130101;
EndDate = 20171231;

If I want to to apply the optimized parameters, from the 5 WFO cycles, for the desired simulation period of StartDate thru EndDate, I have to comment out the NumWFOCycles line, Save, then click Test. The script then reads the parameter values from the .par file and applies it for StartDate thru EndDate.
