The accents added in FE (→GE,EE) may be a result of Chopin's proofreading. However, according to us, it is more probable that they were additionally added by the engraver of FE, who either did not observe the change in accentuation or he considered it to be the manuscript's inaccuracy. Cf. the Etude in C major, No. 7, bars 54-55, C minor, No. 12, bars 2-4.
