There is also this very interesting account given by another break-away schismatic group, the Genuine Orthodox Church under Metropolitan Christopher of Mesogaias and the Islands.

Website of the Genuine Orthodox Church (GOC) - Metropolitan Christopher of Mesogaias and the Islands
This brief history, for the most part, presents a fair account of what happened from 1924 to the current time. It is only five pages long with a little additional information not presented in the currently edited book by Father Stephen Fraser, who never intended to produce a large manuscript but a "brief history and commentary."
For example, this brief history by Met. Christopher jurisdiction gives a hint as to why Met. Chryosostomos of Florina might have been misled from the beginning as he might have thought that the original GOC remained a movement of laity and monastics, which hoped to resist the New Calendarist State Church of Greece and possibly effect a change back to the Old Calendar if at all possible.
More likely, however, is the fact that Met. Chrysostomos was already elderly, had retired from the EP, and had possibly became confused during his time of incarceration. Realize that he was brutally imprisoned at the hands of the Freemasons and New Calendarists shortly after he and two other bishops had consecrated a new Synod of Bishops for the GOC. The New Calendarists used such tactics as yanking out the facial hair, striping off the clerical clothing, and the withholding of food, water, blankets, and sleep in an attempt to brainwash the hierarchs into returning to the State Church. In addition, there are accounts of these saintly men and women being forced to stand upright for days in a very tiny space in an attempt to get them to deny the Holy Faith and Holy Traditions. These inhumane conditions imposed by false clergymen of the State Church of Greece were enough to break some of the bishops, clergy, and laity who had suffered such imprisonment.
Remember that Met. Chrysostomos was a retired bishop under the EP, who had joined the GOC "movement" back in 1935 and had helped create the GOC Synod by co-consecrating four new bishops with the two other State Church of Greece Bishops who had come in repentance to the GOC. However, in 1937, Met. Chrysostomos of Florina and Germanos of Demetrias composed a letter which stated that the calendar innovation was a curable error (same heretical thinking the Cyprianites later had), and that "the State Church is not actually schismatic, but rather only "potentially schismatic" until a Pan Orthodox Synod decides her fate. And until she is judged by such a Synod, her mysteries retain sanctifying grace. This belief goes counter to their encyclical of 1935" (p. 10, Genuine Orthodox Church of Greece (GOC), by Father Stephen Fraser, 2013).
