11 staccato dots in FC

13 dots in FE (→EE)

11 dots in GE1

14 dots in GE2

16 dots suggested by the editors

..

Staccato dots under (over) the bass notes are present in this theme both in FC and FE in the vast majority of cases (we take into account both the discussed bars and their counterparts upon the return of the theme (bars 79-94). The distribution of the bars devoid of dots is certainly accidental, hence in the main text we give them in all bars.
In GE1 and EE the versions of FC and FE, respectively, were inaccurately reproduced. In GE2 the majority of the dots missing in GE1 were added.

In FC and FE the flats lowering c(1) to c(1) are missing. Chopin's patent mistake was corrected in GE and EE.

No markings in FC (→GE)

  in FE (→EE)

..

The pedalling of FE (→EE) seems to be a mistake, even if it was entered by Chopin. The pedalling of bars 25-39, compliant between FC and FE except this place, reveals an easy-to-grasp regularity – the use of pedal is marked only where the bass notes are played separately – a regularity that the discussed markings of FE break.

In this entire phrase, kept in the key of F minor, Chopin overlooked 5 naturals raising g notes (in various octaves) to g:

  • g1 in bars 50 and 53,
  • g in bars 51 and 54,
  • g2 in bar 55.

In EE accidentals were added in bars 53 and 55, while in GE all except in bar 53.
