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 4.9 syringe a week, and it under-forecast by 38% overall. A same-weekday-last-week guess would have been off by 79%. This item had no usage on 67% of days, so the intermittent method is used.
