Pedalling in A

Pedalling in GE1

Pedalling in FE (→EE)

Pedalling in GE2

..

In the main text we give the pedalling of A, since the authenticity of the addition introduced in GE1 (→FEEE) is uncertain. The doubts are raised by an inaccurate alignment of indications in this bar, the absence of the  sign in the previous one and a clumsy arrangement of the 1st beat of the bar. If, e.g. a sequence of  signs at the transition between bars 26 and 27 was originally printed as a whole in bar 27 (considering the 2nd quaver to be the beginning of the bar), Chopin could have added only the most sonically striking mistake, which was the omission of the  sign at the beginning of bar 27.
The version of FE, despite being apparently closer to the notation of A than GE1, was most probably forced by the dense arrangement of the text. In GE2 the additional change of pedal was removed, however, the placement of the previous signs was not adjusted.

 at end of bar in A & GE2

No sign in GE1 (→FE)

 after 5. quaver in EE

..

Omission of the  sign in GE1 (→FE) is certainly a mistake. The sign was added in EE (arbitrarily) and GE2 (after A).

Dots in A & GE2

No marks in GE1 (→FEEE)

..

Omission of staccato dots under (over) the bass notes is certainly a result of inaccuracy of the engraver of GE1 (→FEEE).

4 grace notes in A

3 grace notes in GE (→FEEE)

..

In a proofreading of GE (→FEEE) Chopin removed the second out of four small semiquavers written in A, most probably, however, it was an erroneously engraved a1. In spite of the fact that Chopin's intention of removing the correct note (f1) was not explicitly expressed in this situation, a reduced number of notes in this ornament remains a fact. Due to this reason, in the main text we give the version of the editions.
