Field notes
The Northwind Ops example exposes 2,993 formulas across seven record types and 120 sample orders, including dependencies such as price, discount, tax, and freight. Its displayed checks cover 2,870 values: 2,869 agree with the workbook, while one rounding edge is left for a person to inspect; the page says drafts do not take effect until someone publishes them.
