The use of  time signature surprises only in GE1, as FE did not use the  indication in the Etudes – contrary to the manuscripts – even once, neither in Op. 25 nor in Op. 10 and the Etude in F minor, Dbop. 36 No. 1 (cf. also the Impromptu in A major, Op. 29). In any case, the correctness and authenticity of the  time signature is undeniable with respect to the compatible version of FC and EE. The correct time signature was returned in GE2 (→GE3).

Our variant suggestion

..

According to us, the earlier pedal release than in similar situations may be a result of Chopin's mistake, who, while introducing the pedalling, most probably in the already finished pitch and rhythm text, only saw the change of the chord and did not check its sound. Therefore, in the main text we suggest a variant solution.
The  sign in GE1, placed slightly later, is most probably a mistake.

In the 2nd half of the bar, in FC (→GE1), FE and EE1 there are no sharps raising c1 to c1 and d1 to d1. EE2 (→EE3) completed the second one of them, while GE2 (→GE3) – both.

b. 47-48

composition: Op. 25 No 6, Etude in G♯ minor

..

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.

Lack of the  returning d2 is a typical inaccuracy of Chopin notation. The sign was added only in GE2 (→GE3).
