It is hard to assume that the omission of the crescendo mark or verbal indication was intended here by Chopin – cf. the analogous phrase in bars 33-34. Therefore, in the main text we suggest the  of AI.

According to us, the  hairpins written by Chopin in AI render his intention better than the perhaps inaccurate mark of FE. Shortening the mark in GE1 (→GE2GE4) and EE gives it a rank of a local detail, not directly related to  in the next bar. It can serve as an inspiration to the performer, yet it does not result from the notation of FE, not to mention the notation of AI.

A possible error of the engraver of FE (→GE,EE) is indicated by the repeated  just at the beginning of bar 55. A number of other examples of omission of the letter 'z' in  makes this error highly likely.

No slur in AI & GE4 (→GE5)

Slur in FE (→GE1)

GE2 (→GE3)

Our suggestion

..

The fact of beginning the slur from the 2nd group of semiquavers is almost certainly an inaccuracy of notation, which probably follows from [A]. Different versions of the slur's ending in EE and GE2 (→GE3) are certainly a result of the engravers' errors. The omission of the slur in GE4 (→GE5) may be considered as an oversight or revision.
