Taking into account analogous bar 44, the later pedal depression in FE has to be considered as an inaccuracy. It is hard to assume to whom it could be ascribed and what could have provoked it.

According to us, the authenticity of  does not raise any doubts. In turn,  in FC (→GE) may be a result of an inaccurate interpretation of [A] by the copyist – the 'f' and 'z' letters from some of Chopin  merge in such a way that they can be considered as one 'f' letter, i.e.  (see the Etude in E major, Op. 10 No. 11, bar 25 or 50).

The notation of accidentals in the sources shows significant inaccuracies and differences, which, however, do not cause any difficulties in interpreting Chopin's intentions. Due to the use of an octave sign in some of the sources, it is also unclear which signs have to be considered as necessary.
The most serious mistake is included in EE1, in which in bar 47 there is not a single  lowering a to a. FC (→GE1) and FE include a  giving an a3 before the 1st semiquaver; the sign was added only in EE2 (→EE3) together with a respective  in the L.H. In bar 48 in FC, FE and EE1, the  giving a1 appears only before the 3rd semiquaver; the necessary sign at the beginning of the bar was added in GE1 and EE2 (→EE3), yet only in EE2 (→EE3) the superfluous in this situation sign before the 3rd third was deleted. It is only GE2 (→GE3) that includes the completely correct notation.

The smaller number of fingering digits in FC (→GE) means that Chopin completed the fingering in the base texts to FE and EE. In EE, omission of one of the digits written in FC indicates an oversight of the engraver or the person performing the base text to EE.

The missing fingering digit over the 1st semiquaver in GE3 is certainly a result of wear and tear of printing materials (the beginning of the slur is also invisible).
