874 of 901 products checked against a named source, and the other 27 listed by name
A percussion and pro-audio retailer’s catalogue of 901 products. We checked 874 against a named source and listed the other 27 as unchecked instead of guessing. Because the report says what we could not verify, the number at the top of it is worth reading.
What arrived
A catalogue of 901 products from a percussion and pro-audio retailer. For each product, the job was to compare what the supplier’s file said with a named source and report what agreed, what differed and what was missing.
What we found
We found a named source for 874 of the 901 products. The source’s own search did not index the other 27 at all, so there was nothing to check them against.
What we did
We checked the 874. The other 27 are listed by name at the top of the report as unchecked, and we did not guess at them or quietly leave them out.
The report said so in its first lines, before any finding:
| Line | What the report said |
|---|---|
| Products | Evaluated 874 of 901 products. 27 had no usable source, with the list |
| Attributes | Evaluated 31 of 54 attributes. 23 have no external authority, with the list |
| Evidence | 2,612 source rows, read between 2 and 19 August 2026, up to 24 days old |
What came back
The first line of this report says what it could not check. 874 is smaller than 901, but it is the more useful number, because every finding below it rests on products that were actually checked against something.
How we counted
From the delivered report’s own header. A product counts as checked when it resolved to a confirmed page for that product. The 27 are the products the source’s search did not index.
What it means for your file
Ask anyone who checks or fills your product data, us included, for the number they could not check. A figure with no exceptions listed leaves you to guess which values were checked and which were assumed.
The product data quality checklist lists the checks to run on a catalogue before it goes live.
