In the main text we add a cautionary  to f1.

2 slurs in A, possible interpretation

3 slurs in GE (→FE,EE,IE)

3 slurs suggested by the editors

No slurs, our alternative suggestion

..

The two diagonal lines visible in A over the 2nd half of bar 55 and the beginning of bar 56 were reproduced by GE (→FE,EE,IE) as slurs encompassing 2 subsequent pairs of quavers, which we adopt to the main text. We also include the third slur added by the editions, encompassing 3 subsequent quavers, which are almost certainly supposed to be performed legato as well. However, the A notation is unclear – the range of the first slur is uncertain; the same applies to the very interpretation of these lines as slurs. They could be random lines or an abandoned attempt at writing slurs, which was eventually replaced by the legato indication at the beginning of bar 55. We include these possibilities in the suggested alternative interpretation, in which we apply the legato indication at the beginning of bar 55 to the entire section devoid of slurs (bar 55 and the first half of bar 56).

In A there are visible traces of removal of the bottom note of the 5th R.H. quaver, along with the respective accidental, which suggests that the initial note was e2 instead of g2.

In this harmonic and textural context, the missing  must be considered Chopin's oversight – in the section that ends here the pedalling allows to put the chord specifying the harmonic contents on the previously played bass notes, whereas starting from the next bar, the use of pedal is no longer necessary to build the sound of subsequent chords (although it is by all means possible). The mark was already added by GE (→FE,EE,IE).

In the main text we add a cautionary  to d2. By contrast, we omit the unjustified (cautionary?) flats to a and a1, present in the sources.
