11 assertions · 4 opinions · 33 insights · 3 disclosures · every statement was checked. The predictions and assertions are the 11 claims: statements the public record can support or contradict. 5 are resolved, 1 is not yet assessed, 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.
