+    The *stochastic\_scenario\_end* parameter starts counting from the start of the simulation!
+    In the examples above, when the base scenario has a duration of 6h and the forecast scenarios have a duration of 16h,
+    the forecast scenarios will only be active for 10 hours between hour 6 and hour 16!
