4 not checkable as stated how the 4 claims stand · each chip opens the sources

4 assertions · 1 disclosure · every statement was checked. The predictions and assertions are the 4 claims: statements the public record can support or contradict. 0 are resolved, and 4 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

What the tape says about how Bill argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

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 Bill Peebles on measured tape to publish a rate. This says nothing about how they speak.
