"It is academically dishonest in many places. For instance, on page 14, in the 2nd paragraph from the top, the claim is made that during Russell's lifetime the early Bible Students 'concluded that 1914 had marked the beginning of Christ's heavenly rule.'"
While I agree the document if flawed, I don't think this is a flaw, though it is misleading. Russellites believed Christ's parousia began in 1874, but they taught that Christ's rule over/on the earth would begin in 1914 when the Saints would be "Translated." For instance, Kingdom Come (Studies vol. 3, page 126 speaks of a dispensation, the harvest period from 1878-1914, as lasting "until the overthrow of the professedly Christian kingdoms, really 'kingdoms of this world,' and the full establishment of the Kingdom of God in the earth at A. D. 1914, the terminus of the Times of the Gentiles." Volume 2, Time is at Hand, chapter four, discusses this in more detail.
The issue is misdirection by lack of detail.
