In A, the gruppetto written with small quavers fills the 3rd crotchet of the bar. In GE (→FEEE), small notes started more or less one quaver earlier, which may suggest an erroneous rhythmic layout of the gruppetto.

Before the penultimate note in A (→GE1FE) there is no accidental specifying whether it is to be f2, in accordance with the figuration's logic, or f2, in accordance with the orthographic rules. In this kind of figures, transferred by an octave, Chopin would often omit repetitions of accidentals, considering them to be obvious. The fact that he heard fhere is proved by cautionary naturals before the f1-foctave in the next bar, added in the proofreading of FE (→EE), most probably by Chopin. In this situation, in the main text we adopt the version with f2. It is also in EE, in which a  was probably added after having taken into account cautionary naturals (cf. bar 171). GE2 opted for the version with f2, adding a  before it.

In A (→GEFE) there is no  raising d2 to d2. The patent inaccuracy was corrected in EE, adding also a cautionary  before c2.

In A the only  raising d to d appears in the 1st half of bar 153. Five out of seven necessary signs were added already in GE1 (only two naturals before din bars 152-153 were overlooked), which, taking into account the clarity of the situation, possibly did not require Chopin's participation (although it could have been also him that noticed the missing signs). EE and GE2 have the correct text.

In ½Chopin would try to avoid writing on the cello stave, as a result of which he wrote both  signs before respective bass notes. It also contributed to an earlier placement of the  sign, with respect to analogous bar 152, which in GE1 (→FE) was moved even closer to the beginning of the bar. EE and GE2 introduced some changes in the placement of the signs too (GE2 after A). In the main text we give an interpretation of the notation of A compliant with bar 152.
