Accents in these bars may be interpreted as long (especially in FE, and probably in GC) or short (EE and GE, more probbale in GC). For the main text we adopt short accents because of the notation including rests at the end if each bar - if Chopin wanted to suggest longer sounds, he should have written crotchets. As and additional argument to support this view, we see that in FE in bars 613-616, repeating bars 581-584, there are short accents. In FE there is no accent in 588, which is obvious inaccuracy.
