How it is counted: mention rate = answers naming it ÷ 178 (5 phrasings × 3 repeats × 12 seats = 180 calls, 178 valid); the last two columns count seats, and "stable coverage" means more than half of that seat's 15 answers. Different denominators, so 12 of 12 next to a rate below 100% is not a contradiction.

The sample behind this cell

Valid samples / calls expected: 178 / 180
Completeness: 98.9%
Effective entities (effN): 21.8
Entities mentioned at least once: 98

How this cell was asked

This cell used 5 phrasings, each asked 3 times. Every call asked for the ten names only — no reasons, no scores.

Where this page stops

This is one measurement, not a trend line. The next run of the same phrasings comes next quarter.
Each call collected ten names at most. Anything past the tenth name is invisible in this cell, which is not the same as being absent.
Mention rate is the share of samples in this cell where a name came up. It is not market share, and it is not a judgement about the product.
