In the main text we omit the cautionary  to a1 in bar 283 (present in all sources), and we add it in bar 284. We also include the  to a3 at the end of bar 284 added in GE (→FE,EE,IE).

The extension of the slur in bar 284 in GE is most probably a routine revision assuming that the A slur is inaccurate; actually, it looks as if Chopin stopped writing it after having encountered an obstacle in the form of the a3 quaver. In this context, the similarity between A and the slurs in EE and IE could be puzzling; perhaps the GE slur was changed in the last stage of proofreading – cf. bar 225. In GE (→FE,EE,IE) the described change is accompanied by an earlier starting point of the slur in bar 285, as a result of which all quavers in this fragment are encompassed by slurs. This change is unarguably contrary to the A notation.
In the main text we reproduce the A slurs, as it is uncertain whether they are inaccurate or not – perhaps Chopin wanted to lead the slur from bar 284 to g3 at the beginning of bar 285, which is suggested by the following slurs, or simply embrace a3-g3 with a slur, as he did in a similar situation in bars 73-74.

The change of the type of accent in FE is an inaccuracy, frequent in Chopinesque editions. The absence of the mark in EE is most probably due to the engraver's oversight.

When interpreted literally, the version of the sources, featuring d3 as the 6th quaver, although harmonically possible, is almost certainly erroneous. This is supported by the comparison with analogous bar 288 and 77 and 79, as well as by the role bars 281-292 play in the structure of the finale – preparing the entry of the secondary theme in the key of F minor by consolidating the C chord as the dominant to this key and by reducing harmonic variability and motivic complexity. The highly likely oversight of the  is also indicated by many similar situations in which Chopin forgot that the earlier accidentals were still valid, even the ones put to the preceding note – cf., e.g. bar 5 and 6. Taking into account the above, in the main text we suggest here d3
