The version of the 2nd half of the bar added in AsI seems to be the first version of the final text, hence we regard it as a variant of the latter. However, as upon the return of this bar (bar 19) AsI has only one version, identical to the final one, all three versions can be actually treated interchangeably.

The AsI notation is inaccurate in terms of accidentals – in the principal version the  raising e2 to e2 is written only just in the 4th R.H. figure, while in the added version there is no natural at all. On the other hand, in the L.H. part, Chopin unnecessarily repeated a  to e1 in the 4th passage.

In JC, there is a cautionary  before the third quaver (A), which is completely unjustified in the context of the version of bar 3 written in that copy.

In front of a1, the bottom note of the 4th third, all sources include . The sign is totally unjustified in this place (we omit it in the main text), however, it reveals Chopin's doubt, as far as the notation of the a/a note in the Gkey is concerned (cf. the note to bar 7).

A (→FE) has a cautionary  before the 7th L.H. semiquaver, a1. The accidental was omitted in FC (→GE1), however, EE and GE2 have flats there in both the L.H. and R.H. parts. We also include these signs in the main text.
