In A there is no  before the 1st semiquaver in the L.H., yet it is before the 6th note. However, there are no doubts that both notes are meant to be b. The error was corrected in a proofreading of FE, by moving the  at the beginning of the bar. Moreover, the  before the last semiquaver (f1) was omitted in A (→FE). GE and EE have a correct text in this bar.

Interpretation of A (→FEEE) suggested by the editors

..

In A (→FEEE) the  raising f to f is placed only in the 2nd group of semiquavers. The tonality of D major, consolidated in the previous bars, does not leave any doubt that lack of  before the 2nd note in the bar is another sign Chopin overlooked, due to obviousness of the situation. Writing a  before the 6th semiquaver was probably related to the impression of harmonic change – from the 2nd group in bar 43 to the 1st group in bar 44, the key of F minor transitionally prevails. The sign in the 2nd group confused the reviser of GE, who, believing that it was that was supposed to be in the 1st group, added a cautionary  before the 2nd semiquaver. Chopin would often place an accidental too late, e.g., in bar 42, as well as in other pieces, e.g., Etude in A, No. 10, bar 37, Sonata in B minor, Op. 35, 4th mov., bar 51, the Mazurka in A minor, Dbop. 42B, bar 61, the Concerto in F minor, Op. 21, 1st mov., bar 100, 2nd mov., bar 75.

A is missing the  before the penultimate semiquaver (b). Chopin noticed this patent inaccuracy while proofreading FE, yet initially the sign was erroneously inserted before the last note (d1), which was reproduced in GE1 (→GE2). In the last proofreading of FE (→EE), the  was moved to the right place, a relevant addition was also introduced in GE. In GE3 (→GE4), the superfluous sign before dwas removed.

In A there is no  raising f to f in the 7th semiquaver in the bar. This patent oversight was corrected in FE (→GE,EE).

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.
