Sales estimate
Derived from stock levels falling between polls, over 6 observed days. Intervals where stock rose, or where a variant sat at the store's inventory ceiling, are discarded rather than counted as zero sales.

An estimate, and the page shows what it rests on: which method produced each day, how much of the catalogue could be read, and how many intervals were thrown away. A day marked not measurable is not a day without sales — it is a day we could not defend a number for.
