How the forecast was made
A weighted recent average that learns the weekday pattern and any trend. Recent days count more than old ones.
Report card: the model was fit on history up to Tue Jul 21 and scored on the 56 days after. Weekly totals were off by 11% on average (27% day by day), and it under-forecast by 8% overall. A same-weekday-last-week guess would have been off by 13%.
