How this board is measured
We ask each model the category's questions as a buyer would, read every answer, and count which brands it names. The last 90 days are pooled; each answer counts once. A board is published once it covers most of the category's questions.
Rates carry a 95% range. A brand's rank counts only the brands clearly ahead of it, so close calls tie.
