1 prediction · 10 assertions · 4 opinions · 16 insights · 3 disclosures · every statement was checked. The prediction and assertions are the 11 claims: statements the public record can support or contradict. 6 are resolved, and 5 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.
