Out of the three accents visible in A at the beginning of subsequent quaver motifs, it is only the third one that was repeated in FC. It can be explained by them having been added in A later or, which seems more likely, by the copyist's distraction. It is also unclear which accents Chopin meant: taking into account the whole-bar 
hairpins in similar motifs in b. 53 and 55, we consider long accents to be more likely.
