The performance markings in bars 5 and 13 in A are compatible and understandable: 
and long accent over e
2 underline the local climax after which a 
on the descending semiquaver motif appears (in bar 45 there is only the sign). It is not that clear in the case of the indications included in FE (→GE,EE) – the sign, moved to the 1st half of the bar, if associated with the part of the R.H., is entirely under the long note, which in Chopin's notation is equivalent to a long accent. Therefore, the notation of FE would merely be a simplified version of the indications of A. On the other hand, the notation of the sources discussed in separation from A does not raise major doubts – the climax is underlined by in bar 5 or by the accent in bar 13 and in both cases it is followed by a diminuendo (in EE2 there is no accent in bar 13). The lack of in the repetition of the phrase may be considered as a suggestion to shape the dynamic flow of both phrases in a different way.
In the main text we give the indications written by Chopin in A, with a suggestion of a possible omission of in bar 13. The sources' version, whose scope of authenticity is difficult to determine, yet which to a certain extent could have been inspired by the composer, is considered by us as an alternative solution.
