I'm working on the handbook chapter for Forecasts, and cannot figure
out how the "Day of month to start forecast" is actually used. I have
not yet read the code, but I suppose that will be my next step.
If the cycle is 30 days, and I start with day 0, I get predictions for
30, 60, and 90 days. If I set it to 1, I get 11, 41, 71, and 101
(which is above the 96 Days to Forecast.) That pattern follows up to
19 days (29, 59, 89, 119) but at 20, I get 30, 60, and 90, dropping the
fourth value. With 21, I get 1, 31, 61, 91, back to four cycles.
Any explanations are welcome.
Jack
