The seven accents written in A, in spite of slight differences in length, are certainly long accents. All editions reproduced them as common, short accents, probably due to the fact that in this context they could not be considered diminuendos, which is how Chopinesque long accents were generally interpreted. The absence of the penultimate mark (at the beginning of bar 293) is most probably an oversight by the copyist or by the engraver of FE1.
