  in A

Disregarding A, the hairpins  in GE (→FEEE) were stretched to fill all the available space between con forza at the beginning of the bar and the hairpins   at the end, surely contrary to Chopin's intention.

A more probable interpretation of the accents in A 

Accents in GE

Accents in  FE (→EE)

..

It is not clear whether the accent over b flat1 in A is a long or a short one. We tend to favour the latter option, contradictory to the manner in which it was interpreted in GE (→FEEE).

The second accent in that bar, under b flat2, is clearly a long one in A and in a sense also in GE, in which it has the form of a short diminuendo. In FE (→EE) nobody paid attention to the length of those signs and both accents were given as ordinary short ones.

b. 54

composition: Op. 27 No 2, Nocturne in D♭ major

A long accent in A

Hairpins   in GE (→FEEE)

..

A long accent from A was interpreted in GE (→FEEE) as half-bar long hairpins  . The comparison with the analogous bar 56 resolves any possible doubts as to the meaning of that sign.

 A, graphic reading

 GE (→FEEE)

..

The hairpins in A may be considered slightly too short (which is difficult to notice in practice with the narrowed notation of  A). Still. Chopin could not have intended a half-bar mark visible in GE (→FEEE).
