Where the uncertainty lives
The largest σ contribution in this category is hot lunch service (mixed menu, 460 covers) (64.3% of the category's variance). DEFRA publishes no per-meal factor, so the menu lines use an estimate carried at wide uncertainty, and this line has the most covers of any catering line. Reduction levers that move this line will tighten the band the most.
