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.

How they sound: speaking style how? →

276 words/min while actually speaking · 3 um and uh per 1k words · 13.8 false starts per 1k · 30.8% of pauses land inside a clause

Measured by listening to 10,471 words across 1 episode, but every recording we have of Jean-Denis Greze is the aired feed, and an editor cleaned that audio before release. Some of the hesitation was cut before we ever heard it, so read these as floors: the true rates are at least this high. These are measurements of speaking style, not scores. How it's measured →
