In bars 1 and 5, in the principal AsI version, the R.H. hemidemisemiquaver figures do not advance in parallel to the semiquavers constituting the melody. In the 1st half of bar 1, Chopin already added an alternative version, close to the later A version. According to us, this version is to be considered a draft of a new idea, containing the default instruction 'and so on and so forth'. This is indicated by analogous bar 17, in which the A version is marked in the form of a similar addition throughout the entire bar. We provide the AsI addition interpreted as such as a variant of the later version in both bars (1 and 5). See also bars 2-6 and 7.

In AsI the 4th hemidemisemiquaver figure in bars 1 and 5 is the same as the third one, although the semiquaver ending the passage is different – D instead of B1. Moreover, this semiquaver was changed in the stage of writing AsI, which is proven by the visible corrections to this note in bars 1 and 21. Back then Chopin settled for the correction of the bass line only, since in the stage of writing AsI he would use other intervals than an octave between the last hemidemisemiquaver and the following semiquaver much more frequently than in the final version.

As in bars 1 and 5, in AsI the R.H. hemidemisemiquaver passages are not moved in parallel with the melody semiquavers. This is the initial version, subsequently simplified by reducing the number of large leaps.

In AsI there are no flats restoring b3 at the end of bars 2 and 6. This is a patent mistake – Chopin wrote 'b' over each of those notes. In A those flats are present, yet the accidentals to the 4th note of the 2nd and 4th R.H. passages, a  (b2) and a  (b2), respectively, are missing. This inaccuracy does not create any doubts concerning the text either.
A similar situation is to be found in bars 18 and 22

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.
