8 predictions · 12 assertions · 9 opinions · 11 insights · 2 disclosures · 2 what ifs · every statement was checked. The predictions and assertions are the 20 claims: statements the public record can support or contradict. 6 are resolved, 2 are not yet assessed, and 12 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

The record, in short

This is a score against a rubric. It is not a rank. Every host question → answer exchange is scored with names hidden on directness, coherence, precision and compression, 1–5 each, on meaning alone: disfluencies are ignored, and only raw unedited episodes count. This is the score that measures thought. Every scored exchange, scores shown → · The rubric and its checks →

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Marc Andreessen on measured tape to publish a rate. This says nothing about how they speak.
