Originally, the part of the L.H. in this bar was a repetition of bar 10. Unlike in the previous bar, here one of the presentation autographs – AIII – already includes the final version. The version of AII is most probably Chopin's mistake.

On the basis of the photocopy of A we have at our disposal, it is difficult to state whether on the 2nd and 3rd crotchets in bar 19 Chopin wanted to have a notes or not. FE (→GE,EE) includes a-c1-gchords, however, the engraver could have mistaken this bar with bar 17. A few different versions, which are included in bars 11-12 and 19-20 in the accompaniment of As, AI, AII and AIII, as well as deletions performed in these bars in A prove that Chopin was looking for the smartest version, as far as the sound and piano issues are concerned, until the very end. Giving bars 11 and 19 the same form seems to be justified due to the sound economy and thinking with pairs of bars (bars 17-18 and 19-20), therefore, we give this version in the main text.
Similarly in bar 91.

In this bar, the differences between the presentation autographs and the final version result from the need for a smooth transition with the next bar, in which Chopin used a different version of accompaniment, while writing autographs-gifts and yet another one, while preparing the Waltz for print. Therefore, the presented variants may be rationally used only with a corresponding version of bars 21-24. The notation of As is problematic, as Chopin did not write a version of bar 20 which would combine with the tenor-linear version of the L.H., written in the sketch as second and adopted in our reconstruction of As – see bars 21-24 – at all. We assume that the situation implies repetition of the version of bars 9, 11 and 18.

Moreover, it seems to be incomprehensible why the correction of the version of As, which is clear in A, was not initially included by the engraver of FE neither in this bar nor in its repetition in the reprise, as a result of which it had to be redone in the proofreading of this edition. It suggests adding changes in A already after having engraved FE, probably at the time of proofreading. Cf. Polonaise in E minor, Op. 26 No. 1, bar 20.

Already in As, Chopin wrote two versions of accompaniment in these bars and in bar 24, however, it is not clear how he planned to use them. Eventually, in all later sources they were used to diversify the repeating figures through differentiation of the part of the L.H. in bars 21-24 and 29-32. The presentation autographs and the published version differ, however, in the order of appearance of both versions – apart from minor details, AI, AII and AIII first include the "tenor" version, which in A (→FEGE,EE) appears only as the second.
In order to preserve the continuity of the bass line after a possible version change, in the context of this note, one has to choose one of the corresponding variants in bars bar 20 and bar 24.

In the main text we add a cautionary  before e1 in bar 21, after the authentic sign before g1 in bar 23.
