How the forecast was made
This item is used on fewer than 60% of days, so the forecast is 'how much when it's used' times 'how often it's used', each updated daily.
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 1.1 vial a week, and it under-forecast by 56% overall. A same-weekday-last-week guess would have been off by 100%. This item had no usage on 86% of days, so the intermittent method is used.
