How to read this

A category is asked six ways of each of fourteen models on behalf of each buyer segment, so a segment is eighty-four answers. An answer belongs on this page when the judge labeled Stellar Cyber Open XDR neither its first choice nor an alternative in it; the products listed are the first choices those answers made, counted once per answer. An answer that named nothing first, or named Stellar Cyber Open XDR only in passing, is in the denominator and adds to no product. The counts are not the category standing, which is on the category page with its share and rank; they are the same record read from Stellar Cyber Open XDR's side.

The output is the models' output; nothing here is a recommendation by the index, and a product named instead of Stellar Cyber Open XDR was named by a model, not endorsed by anyone.
