Initially, the 1st group of semiquavers in A was . Chopin deleted it and wrote the final version below. It seems that he did not check the influence of the change on the notation of the subsequent part of the bar – there is no  before the 3rd note in the 2nd group of semiquavers, while in the 3rd group there remains a  before g, which is however justified also as a cautionary accidental, yet it was written probably due to g in the original version.

In A there is no cautionary  before b1 at the beginning of the bar. The sign was added in FE (→EE), probably during the last proofreading, as it is absent in GE1. In subsequent GE,s it was however completed, while in GE3 (→GE4) a  before b2, the 4th semiquaver, was also added.

A includes a  before the penultimate semiquaver (superfluous), in turn, it does not include any sign before the last one. This patent oversight was corrected already in a proofreading of FE1 (→FE2,GE,EE). In the main text we omit the superfluous  before f3.

At the beginning of the bar A have  before e1. The unjustified in this context sign was removed in the last proofreading of FE (→EE), not included in GE.
Also the  before the 3rd semiquaver in bar 75 is not justified with the previous flow of the music, yet we leave it due to e in the L.H. appearing in the middle of the bar.
