g2 instead of f2 at the last quaver of the bar is certainly a mistake of Chopin in [A]. It is proved by the  before the note, present both in FE1 (→FE2) and GC, which originally also included g2. Chopin corrected the mistake in GC and the proofreading of FE3 (→FE4). The erroneous version was passed down to EE1, in which it was revised, by deleting the , which was superfluous before g2.

At the beginning of the 2nd half of the bar before the bottom note of the second, GC and FE1 (→FE2) have one  before each of the notes instead of . This easy to detect mistake – none of these flats is necessary at this pitch, whereas a1 appears in the part of the L.H. – was corrected in GE, by adding another  before the bottom note. The correct notation is included in FE3 (→FE4) and EE, which in both cases could have been a result of Chopin's intervention.
A double flat before the top note of the penultimate chord was added only in GE and EE2.

It is hard to state whether the  added – probably by Chopin – in FE4 was a correction of a mistake or a change of the concept. According to us, the first possibility seems to be more likely.

The slurring of particular sources seems to convey Chopin's idea only approximately. In the main text, we suggest an interpretation of the slurs of GC based on the slurs written in a more precise manner in analogous bars 57-60. See also bar 189.

FE1 (→FE2) features an E as the 1st note in the L.H. This striking mistake was corrected only in FE3 (→FE4) and EE. In spite of the fact that it was Chopin that prepared both the proofreading of FE3 and the base text to EE, this kind of correction could have been prepared also by a reviser.
