The cautionary  before fwas added in GE (→FEEE). It seems to be highly unlikely that such a minor addition was performed by Chopin himself, but it cannot be excluded – cf. the note on d3

The version of the editions may be a result of Chopin's proofreading in GE1 (cf. the 1st mov., bar 87). According to us, it is a mistake of the engraver that is more likely in this situation – a comparison of three analogous bars (bars 8, 27 and 76) suggests that Chopin gradually differentiated the rhythmic aspect, without changing the melodic scheme, in which the gnote appears only in the end of the bar. The version with the ggrace note, meanwhile, does not add anything with respect to rhythm; in turn, it interferes with the melodic scheme through the premature appearance of g2. Due to this reason, in the main text we leave the version of A.

The version of A is, according to us, the only authentic text of this place. The sixth in GE (→FEEE) is almost certainly a result of a misinterpretation of A – the engraver of GE1 considered the original ending of the stem of the g quaver with a characteristic "hook" to be the B note. Deletion of this note in FES is probably a mistake too – the person who wrote this, perhaps Chopin himself, seeing two notes, out of which one was to be deleted and the other preserved, combined these two thoughts in one activity, by deleting the note that was supposed to stay (a similar mistake was committed in FES also in the Sonata in B minor, Op. 58, the 3rd mov. – in bar 28 a  was added, confirming the erroneous text, instead of the mistakenly overlooked  lowering a1 to a1).

The  returning ein the descending fragment of the roulade is absent in all sources, which is undoubtedly Chopin's mistake. EE added flats restoring e2 and dat the end of the bar – an addition justified in the original notation with the use of an octave sign in the uppermost fragment of the roulade.

The version of the editions certainly stems from a mistake of the engraver of GE1.
