..

The deletion in A allows one to see that originally Chopin wrote the sixth e2-c sharp3 as the 3rd quaver of the bar. The change was probably made after the whole bar had been written in - the proof of that is the   raising c2 to c sharp2 in the second half of the bar.

All the sources have the unnecessary  before c sharp2, the lower note of the 3rd semiquaver. This is probably a remnant of the initial version of the 3rd quaver of that bar.

Quavers in A & GE2 (→GE3)

No quavers in FC (→GE1) & FE (→EE)

..

Just like in b. 34-35, Chopin changed the pitch of the 2nd and 4th notes in A from g1-f1 to b1-a1. In this case, however, the crossing-out of both noteheads also includes the stems (pointing downwards) of the separated quaver voice, which resulted in it having been overlooked both in FC (→GE1) and FE (→EE). Assuming a mistake, GE2 (→GE3) separated both notes after the previous bars.

Before the top note on the 7th semiquaver, the  returning f is only in GE4 (→GE5). It means the sound of f in AI and in the aforementioned GE, and in the remaining sources. However, there is no doubt that the missing  is Chopin's oversight, related to the correction on the 2nd semiquaver.

 in Atut

No marking in FE (→GE,EE)

..

 at the beginning of the bar was written in Atut in place of the previous . The absence of a marking in FE (→GE,EE) means that the engraver of FE probably did not understand this correction, considering the  mark written in bold font to be a deletion of . In the main text, we preserve the version of Atut, in which Chopin reviewed and corrected the dynamic markings – cf. e.g. bar 20 and 32
