5 staccato dots in A1

6 dots in CJ

No marks in CK (→CB) & EL

..

In A1 the dot concerning f2 may be under the number 13. The absence of dots in CK (→CB) and EL is most probably Kolberg's oversight.

e1 in bars 61-62 in A1, CK (→CB) & EL

e1 & e1 in CJ, literal reading

e1 & e1 in CJ, contextual interpretation

..

Out of the two versions coming from [A2], we give priority to CK due to its compliance with the unequivocally authentic version of A1. The sharp raising e1 to e1 in b. 61 in CJ could have been placed by mistake, e.g. due to the resemblance of the figures in b. 61-63. On the other hand, one cannot rule out that Chopin wanted to introduce a major variant of the tonic already in b. 61 – cf. the major endings of the Nocturnes in E Minor, WN 23, C Minor, Op. 27 No. 1, F Minor, Op. 48 No. 2 or F Minor, Op. 55 No. 2, consisting of a few or several dozen bars.

No slurs in A1, CK & EL

Slurs in CJ

Slurs in CB

..

The missing slurs in CK may be explained by the copyist's distraction at the end of the work – he also overlooked the  mark. The longer slurs of both hands were added by Balakirev, just like the vast majority of the remaining slurs of CB.
