b. 32

composition: Op. 10 No 6, Etude in E♭ minor

 in A (→FEGE1GE2)

No sign in EE2

Long accent in EE3 (→EE4)

 in GE3 (→GE4GE5)

..

In EE2 the  mark was omitted and in EE3 (→EE4) it was added in the form of a long accent over the octave in the L.H. In GE3 (→GE4GE5) the hairpins occupy the entire 1st half of the bar.

b. 34

composition: Op. 10 No 6, Etude in E♭ minor

e1-f1-d1 in A

e1-f1-d1 in FE (→GE1GE1aGE2, →EE2EE3)

e1-f1-d1 in GE3 (→GE4GE5) & EE4

..

Chopin changed the original version (written in A) while proofreading FE (→GE1GE2, →EE2EE3). At the time of proofreading, the unnecessary  before e1 in the 2nd half of the bar was left. This may have incited the reviser of GE3 (→GE4GE5) to change e1 to e1 in the chord at the beginning of the bar (this totally arbitrary version was also repeated in EE4).
We add a cautionary  before f1 on the 2nd semiquaver.

The shift of the  returning a1 was certainly performed by Chopin who introduced a few changes in this section of the Etude with respect to the version of A.
