The ranking

How to read this page
- What it measures
- Which names these models produce when asked cold, from what they learned in training. It is not a review, a rating or our recommendation, and a business missing here may simply be one the models were never shown.
- Why the ranges matter
- 36 answers is a sample. Asked again next month, most shares will move by a few points; the ranges say how far they could move by chance alone.
- One business, several spellings
- Branches, legal suffixes and spellings of one business are merged, and the other spellings are printed under its name. Names that might be two businesses are kept apart.
- A name is wrong
- If a business here is closed, misnamed or yours and you want it removed, tell us. We correct or remove it when the page is next published.
