6 predictions · 33 assertions · 13 opinions · 2 insights · 4 disclosures · 2 what ifs · every statement was checked. The predictions and assertions are the 39 claims: statements the public record can support or contradict. 26 are resolved, 1 is 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.

How they sound: speaking style how? →

232 words/min while actually speaking · 5.1 um and uh per 1k words

No argument clarity score for Matt Mahan: no usable question→answer exchanges on raw tape (a fair score needs 8+). We do not score a sample that small. Roundtable and news formats yield far fewer direct exchanges than interviews. Their coarse estimate from 14 exchanges on the produced feed is ≈4.0/5, shown at half point precision because the sample is small and produced tape scores higher.

Measured by listening to 10,479 words across 1 episode, but every recording we have of Matt Mahan 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 →
