Both the verbal tempo indication and the metronome marking were added—undoubtedly by Chopin—during his proofreading of FE (→GE,EE).

b. 1

composition: Op. 25 No 7, Etude in C♯ minor

..

In GC (→GE1) and EE there is no  returning f at the beginning of the 2nd group of semiquavers of the introduction, which almost certainly corresponds to the notation of [A]. It is a very typical mistake of Chopin – cf., e.g., the Nocturne in Cminor, Op. 27 No. 1, bar 83, or the Impromptu in A major, Op. 29, bar 71. The sign was added in the proofreading of FE, most probably by Chopin, as well as in GE2 (→GE3).

b. 1-2

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

The slur embracing the bass motif, visible in GC (→GE), was probably overlooked by the engraver of FE1 (→FE2EE1). It was then added in the proofreading of FE3 (→FE4), probably as a result of Chopin's intervention. The sign was also added in EE2.

No mark in GC (→GE)

Accent in FE (→EE)

..

The accent could have been added by Chopin in [A] (→FEEE) after GC had been already prepared and as such could represent the latest concept of determining the performance manner of the beginning of the Scherzo.

Shifting the  hairpin so that it starts from an upbeat, is, according to us, rather an inaccuracy of the engraver of FE, hence, in the main text we give the undoubtedly authentic sign of A. However, since an alternative possibility of Chopin's proofreading in FE cannot be entirely excluded, the version of FE, repeated in all remaining editions except for GE2no2, can be considered to be a potentially authentic variant. In turn, shortening the sign in GE2no2 is undoubtedly a revision, as a part of which the  signs in all analogous bars were unified (bars 1-2, 5-617-18 and 21-22).
