The version of FE seems to be a result of a misunderstanding at the time of interpreting [A], in which possible corrections (combined slurs?) could have impeded figuring out Chopin's intention. The versions of GE and EE must be arbitrary revisions of this most probably inaccurate notation. The notation suggested in the main text, modelled after the previous element of the progression, is practically tantamount to the notation of FE.
