Every category is asked on behalf of three buyers: a small B2B company, a mid-market B2B company, an enterprise B2B company. Each buyer gets its own standing, computed within its segment and never pooled. This page reads the seventy-three standings side by side: five categories have one leader for every buyer, thirty-five change leader once across the three, and thirty-three have a different leader for each.
A product leads somewhere in 141 cases across the seventy-three categories; ninety-two of those products lead in exactly one segment of one category and nowhere else. The public standing on each category page is the mid-market one; the other segments are one link away on every category page and are never added to it.
What this measures is the answer, not the buyer: the same models, asked the same six ways, told a different company size. Whether that reflects the products or the models' reading of them is not something the index can say.
