ChatGPT, Google AI Mode, Gemini and Perplexity often name different brands and cite different sources for the same question. A brand can lead on one app and be missing on another. Averaging them into one number makes both facts disappear.
Answers also change from run to run. A named rate built on one run per question is noise. Run each question several times on each app, report the count (for example, named in 6 of 10 answers), and show the range that sample supports.
