We give the accents appearing in PE over the chords on the 3rd beat of bars 52-53 and 60-61, which are beyond any source and stylistic doubts, in the main text. In JC, there is only the first of them, which is most probably meant to be understood as a draft suggestion of the same notation. The version of EF with 
markings, which Chopin used only occasionally, must be considered to be non-authentic in this situation.
