The problem is that oos Test period depends on NumWFOCycles. So, wfoprofile script compares apples to oranges.
For EndDate=2022 and NumYears=5, with NumWFOCycles=12, the test period starts in 09/2021, with NumWFOCycles=6, it starts in 05/2020.
Calculating a different StartDate depending on NumWFOCycles is probably possible. But is there a simpler/ready solution?
