Our variant suggestion

..

Chopin's annotation in FED establishes a different dynamic concept of this transition here. According to us, it is at least equal with the version of A (→FEGE,EE). However, as it cannot be excluded that according to the composer's intention the change was only a suggestion connected with the personality or capabilities of a certain pupil, in the main text we limit ourselves to giving information on this alternative concept.

A variant written into FED

The additions in FED and FEFr may be regarded two versions of the same musical idea - syncopations in FEFr show the rubato performance of the quavers in FED.

No marking in FE & EE2 (→EE3)

in FED

..

The dynamic indications of the final part of the Etude were almost certainly added by Chopin to the three, generally finished, Stichvorlage manuscripts. In bars 28-31, EE1 transferred the most elaborately developed version with  in bar 28 and diminuendo in bars 30-31, A (→GE) includes only , while FE, devoid of indications, remained in the shape preceding the additions. Circa 10 years after the publication of the Etudes, Chopin added here  in a pupil's copy (FED), which, according to us, is to be considered as an alternative dynamic concept and not a conclusive change.
Deletion of  in EE2 (→EE3) is most probably related to the addition of fingering after FE.

A variant added in FEFr

..

The variant given by Franchomme seems recom­mendable as a variation of the motif upon its repetition that is very characteristic for Chopin.

Quavers in FES

..

The written in FES version with a chromatic, quaver progression of the bass constitutes a diversification of the transition to the D major section, referring to the ending of bar 22, same as the original transition refers to bar 14.
