What has actually been checked
913 checks across 33 products, all passing. A check recalculates one figure outside Excel and outside Google Sheets, through an independent engine, and compares it to a value worked out by hand from the statute before the run. Each product page lists its own checks by name. The figures themselves are in the workbooks.
This page exists because the licensing argument rests on the checking, and a number you cannot confirm is not evidence. The full report for one product is here.
