In a Q&A exchange, Neville distinguishes true vision from astral projection and says he has had voluntary (and involuntary) out-of-body experiences from the time he had just turned twenty.
Date (happened)
c. 1925
relative · probable · preferred
Reasoning
Neville dates the onset of his voluntary out-of-body experiences to just after turning twenty. His birth date, 1905-02-19, is independently corroborated elsewhere in the corpus (a Wikipedia bio passage and a genealogy research note both agree), putting his twentieth birthday in February 1925. Held to circa/probable since 'just turned twenty' is an imprecise, decades-later recollection with no month or day given.
between 1925 and 1969
stated
between 19 February 1925 and 3 October 1969
estimated · probable
Why
Lower bound is exact-day via the birth anchor; the true first instance may be some weeks or months after 1925-02-19.
Reasoning
Anchoring on Neville's established birth date (hist_event 950, 1905-02-19), 'just turned twenty' cannot be earlier than 1925-02-19; this tightens the previously recorded bare-year start (1925) to an exact-day lower bound. The end of the range is set to the corrected telling date 1969-10-03 (see the told claim appended alongside), the latest point at which the ongoing ('time and time again') practice is attested. Confidence held at probable because 'just turned' is an approximate phrase, not an exact date statement.
Told / reported
3 October 1969
stated
Reasoning
The lecture's own removed chrome dateline gives October 3, 1969 and is marked certain; it directly contradicts and outweighs the catalog claim's October 2, which has already been demoted to doubtful for that reason at the lecture level. The processing note's summary line ('delivered 1969-10-02') is the older, superseded reading.
2 October 1969
stated · doubtful
3 October 1969
estimated
Why
Appended beside the standing 1969-10-02 certain claim per append-only; that claim rested on the demoted catalogue date.
Reasoning
The existing told claim (1969-10-02, certain) matches only the lecture's doubtful catalogue delivery date (#595, itself flagged as contradicted by one day by the lecture's own chrome dateline). Node 1483's certain, preferred delivery claim, read from the chrome dateline '10/3/69', is 1969-10-03. The telling date is corrected here to match the certain evidence.
