How to read this
Share is the percentage of sampled ChatGPT responses to a question that named the firm at all — a measure of visibility, not of the work. A capable firm little has been written about will score low, which is a fact about how often it gets named and not a verdict on whether to hire it.
"Too close to call" is a result, not a gap in the data. Firms are grouped into tiers holding every firm the sample cannot statistically separate from that tier's leader, so two firms in one tier are reported as level however their percentages happen to fall. On 2 of these 6 questions that is what the measurement supports, and saying otherwise would be inventing precision.
Nothing here is our judgement of who is good. It is a count of who gets named. Both firms are measured over the same questions and the same 1050 responses, so neither is being scored on a sample the other did not face.
