Generally speaking, the long accents added in GE are justified – Chopin indicated such a performance in the two preceding four-bar sections, as well as in bars 40-55. He used long, short and vertical accents and 
marks (in various configurations). Due to the above, although the very accenting results from the preceding phrases, it is difficult to say which marks would be used here and next to which chords, hence in the main text we neither include the GE accents nor suggest our own ones.
In the remaining editions the GE accents were reproduced inaccurately, as short accents.
