The presence of two  signs in EE may be explained as a revision, in which the sign in bar 16, compatible with the remaining sources, was completed with hairpins in bar 15 following bar 7. However, both signs can be authentic and it cannot be excluded that they are to be interpreted as one longer diminuendo.

According to us, the wedges visible in A in bar 15 (repeated in FE) and at the beginning of bar 16 (omitted) remained non-deleted as a result of Chopin's distraction. The distraction is proven by the rhythmic error committed earlier in this bar, while the intention to delete the staccato signs is proven by deletions of the signs or entire chords in the 1st half of bar 15 and a few previous bars. In the main text, we give three wedges in bar 16, added probably by Chopin in FC (→GE) and signalised also in EE (cf. bar 16).

In GE1, the  before the last third was misplaced next to the bottom note. The error was corrected in GE2 (→GE3).

The shorter slur of A (→FE) was extended in FC to the end of the bar. It is hard to suspect Fontana of such an arbitrary decision, hence it is almost certainly a Chopin correction. It allows us to consider the wedges present only in FC (→GE) to be most probably authentic.

The initially written here three slurs, one in each bar, were then extended by Chopin in both preserved manuscripts, who connected the slurs between bars 18-19 in A, whereas in FC – between bars 17-18. In A, the situation is additionally complicated by the new line of text beginning in bar 18, as a result of which – as it is often to be encountered in Chopin autographs – it is unknown whether the slur in this bar is supposed to continue the one from bar 17 or not. The two possible interpretations resulting from this situation are reflected in the versions of FE and EE, which, however, feature the most probably inaccurately written ending of the slur in bar 19. In turn, GE inaccurately reproduced the ending of the slur in bar 18. In the main text we give the slurs of FC, corrected by Chopin's hand and compatible with the phrasing corresponding to the formal structure.
