In plain language — In May 1974 Hurst described in his own words what followed his initial research: Decision Models in 1969, CycliTec aids in 1971, and a complete course in 1973. This is the missing primary source for dating that transition.

Source and level — This is a Hurst-signed primary source for the chronology and terms named in the article. It attests the existence of the CycliTec course and services, but it does not replace a complete course copy or independently prove the methods' effectiveness.

What the source documents

The author note states that Hurst founded Decision Models, Inc. in 1969 to develop decision theory and wave concepts for the stock market. It adds that the computerized CycliTec aids were initially published in 1971, followed by a complete training course in 1973.

The references identify CycliTec Services, 500 Sansome Street, San Francisco as publisher of stock and commodity chart services and of the 1973 CycliTec Services Training Course. In the conclusion, Hurst says the methods had been in field use since December 1971.

Why it changes technical provenance

The article is more than a biography. It directly describes formal phasing analysis, the periodogram, envelope analysis, the current cyclic model, and diamond marks below price. It also names time translation, Future Lines of Demarcation (FLDs), and Valid Trend Lines (VTLs).

Cyclepedia can therefore attribute those terms to a signed Hurst source from 1974. Detailed procedures — such as Entry, Extension, and Completion or offsets for different FLD variants — still rely on later post-Hurst expositions until a complete primary copy of the course is available.

Decision Models and CycliTec are different claims

The source explicitly says that Hurst founded Decision Models. It also says that CycliTec published aids, services, and the course, but it does not say that Hurst founded or owned CycliTec Services. Treating the two companies as interchangeable would turn documentary proximity into an unproven fact.

Likewise, “in field use since December 1971” is the author’s statement. It establishes the chronology he reported; it is not independent performance validation.

A bibliographic discrepancy worth preserving

The article’s reference lists the Prentice-Hall book as 1971. The volume examined by Cyclepedia and library records date it to 1970. Cyclepedia retains 1970 for the book edition and records the discrepancy here rather than hiding it.
