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.

8 different accents in GC

8 different accents in GE

6 short accents in EE1

8 short accents in EE2

8 long accents suggested by the editors

..

The accents in GC are of different length, which, considering the similarity of the motifs, is most probably an inaccuracy. In the main text we adopt long accents, which prevail in the notation. All the versions of the editions are most probably a result of an inaccuracy or revision.
