He says he dived backwards and forwards many times as a boy all over the area where he was born, so the sensation of diving backward was familiar to him.

Reasoning
Qualifying passage ids [534721] belong to telling lecture nids [1248]. Each listed lecture contributes the selected safe envelope year 1966 (MAX of its non-refuted delivery years); 1966 is the MIN across telling lectures.
before 22 November 1966
bound
Why
Tightens the phase4 L6a envelope from before 1966 to before 1966-11-22.
Reasoning
L6a envelope tightened to the telling day of nid 1248 (certain delivery 1966-11-22); same premise, finer precision. The phase4 L6a bound on this event is `before 1966`, an envelope over delivery YEARS computed without reading text. Its premise is that the fact is true by the time it is told; on that same premise the DAY of the telling is a strictly better upper bound. Nothing is re-decided — the bound is stated to the precision the evidence always supported. The delivery claim for 1966-11-22 on nid 1248 is held at `certain` by the corpus, which is what carries this claim. #2274; the L6a row stands beside this one.

bound
Reasoning
The prior physical dive predates node 1248 authoritative certain delivery on 1966-11-22.

Why
M7 dating pass (529; 525's readers, packet 013)
Reasoning
Passage 534721: 'as I have done from a high-diving board, backwards'. Event 18038 (c. 1910 to 1922, Barbados) is his recollection of diving backward and forward through boyhood. He could have dived later, so this is an inference with room.
Told / reported
28 November 1969
estimated
Why
Told in Christian Mystery Experienced Biblethroughneville (nid 1844), delivered 1969-11-28.
Reasoning
The sole witness belongs to lecture nid 1844, whose independently corroborated preferred delivery claim is exact and certain for 1969-11-28. Because this told date is inferred from the lecture node rather than stated in the witness passage, it is typed estimated per #2117.
