The version of GE1 (→FE→EE) is a result of Chopin's proofreading, which is proved by the traces of deletion of c1 on the 5th quaver in the bottom voice. However, a more detailed analysis of traces of corrections in print proves that it was also g2 that was being removed there. It means that Chopin most probably did not proofread the text of A, which was fine, but the false c1-a
1-c2-g2 chord: 
. Concentrated on correcting the sound in the place of mistake, it is possible that the composer did not thoroughly check the context and resolved the e1-d2 seventh to the a1-c2 third, particularly since a similar shape of accompaniment appears three bars later in bar 286, very similar in terms of harmony. Moreover, taking into account the possibility of an accidental removal of the correct c1 note as a result of a misunderstanding at the time of implementing the proofreading, in the main text we give the version of A. The proofread version of GE1 can be considered an equal variant.
