Bar 3 in A (→FEGE1GE2GE3) repeats the  from the 1st half of the bar before in the 2nd half of it. The  before f in the 2nd half of bar 4 is similarly repeated. The unnecessary signs were removed in GE4 (→GE5). In analogous bars 11-12 and 43-44 the signs do not appear in any of the sources.

c1 in A (→FEEE2EE3)

c1 in GE & EE4

..

In the main text we give c1 after A (→FEEE2EE3). A similar harmonic progression is often to be found in Chopin's works, e.g., in the Etude in E major, No. 11, bars 23-25, therefore, there is no reason to suspect that Chopin overlooked a  in this place. However, in GE (and EE4) a  was added before this c1, changing it into c1. Completing the missing accidentals was the basis of revision in GE, yet Chopin's intention was not always correctly identified (cf., e.g., the Etude in C major, No. 1, bar 46A minor, No. 2, bar 7A major, No. 10, bars 23 and 35). A similar change of cinto c1 was performed in the ending of the Nocturne in B minor, Op. 9 No. 1, published a little bit earlier in the same publishing house (the 11th quaver in bar 83); the change, being an obvious mistake, shows the schematic approach of the edition's reviser.
