b. 14

composition: Op. 25 No 10, Etude in B minor

..

FE and EE have no sharps returning f2 and f at the beginning of the 2nd half of the bar. This patent oversight was corrected by Chopin in GC (→GE), when he added the necessary signs.

b. 15-16

composition: Op. 25 No 10, Etude in B minor

Two long accents in GC & EE

No marks in FE

Two short accents in GE

..

Lack of accents in FE must be considered as an inaccuracy, Chopin probably corrected this fragment (bars 15-21) in the base text to this edition less carefully – cf. notes to bars 17-1920 and 21). The short accents in GE are a result of misunderstanding the idea of the long accent by the engravers and revisers.

b. 17-19

composition: Op. 25 No 10, Etude in B minor

Eight long accents in GC

No marks in FE

Nine long accents in EE

Eight short accents in GE1

Nine short accents in GE2 (→GE3)

..

Lack of the accent at the beginning of bar 17 in GC (→GE1) at the beginning of bar 17 is most probably Chopin's oversight, who would add accents in these bars in GC. The sign is present in EE, whose base text was also probably completed by Chopin in this way. The accent was added in GE2 (→GE3) too. In FE there are no accents of dynamic character in bars 15-20.

In GE all accents were interpreted as shorts, contrary to the compatible, distinct notation of GC and EE (cf. the short accent in bar 20).

b. 18

composition: Op. 25 No 10, Etude in B minor

..

In GC and EE1 (→EE2) there is no  returning c in the last chord in the L.H. The sign was added in GE and EE3, and probably also in the proofreading of FE.

b. 20

composition: Op. 25 No 10, Etude in B minor

 below L.H. part in GC (→GE1) & EE

No sign in FE

 between staves in GE2 (→GE3)

..

When adding the  sign, Chopin probably omitted the base text to FE (see bars 15-16). The placement of the sign under the bottom stave could have resulted from the will to connect crescendo with the progression in the L.H. or due to lack of space between the staves. In the case of the latter, shifting the sign in GE2 (→GE3) would have been justified.
