The 
mark in FE (→GE,EE) is one of a few that had already been printed in FEcor. Therefore, its compliance with Chopin's intention is not certain due to the possibility of reversing the direction of the sign as a result of the engraver's error (cf., e.g., the Etude in C minor, No. 12, bar 53). Such an error seems to be possible if we take into consideration the four-bar section which ends here and the recurring first phrase with its crescendo and a possible in Ap.
