Additional Information on Reforecast Interactions

If you check the Automatically reforecast before refresh check box in the General tab, then all the data shown from intervals before the current time are reforecast values that were calculated just prior to that interval.  

For example, at 8:02 the actual data from the 7:30 to 8:00 interval is available and will be used to calculate the reforecast for the interval from 8:00 to 8:30 and all the intervals from 8:30 to the end of the day.  At 8:32, the actual data from 8:00 to 8:30 will be available and will be used to calculate the reforecast from 8:30 to 9:00 and all the intervals for the rest of the day.  It will overwrite the 8:30 to 9:00 reforecast calculated at 8:02 with the newly reforecast value calculated at 8:32 since it should be more accurate now with more information. This continues throughout the day so that the 8:00 to 8:30 reforecast was calculated at 8:02 using the sliding window data available at that time, the 8:30 to 9:00 interval was reforecast at 8:32, the 9:00 to 9:30 interval was reforecast at 9:02 and so forth.  Note that I’m using the default values to reforecast every 30 minutes starting with the 2 minutes offset after the hour.

If you uncheck the Automatically reforecast before refresh check box, then all the reforecast data is handled manually. Whenever a user manually does a reforecast, the data for the rest of the day is calculated and it overwrites any existing reforecast data from the current interval to the end of the day.
