suggested by the editorsThe 
hairpin at the beginning of bar 94 in FE (→GE,EE) is almost certainly a typical mistake by the engraver – cf. similar motifs in bars 93-94 and 96-99, particularly the first one in bar 96, which is a variant of the discussed one. This mistake, consisting in reversing the mark as if in a mirror image, can also be found in other pieces by Chopin, cf., e.g. the Nocturne in D
, Op. 27 No. 2, bar 6, Scherzo in B minor, Op. 20, bar 306, Etude in C minor, Op. 10 No. 12, bar 53 or Prelude in E, Op. 28 No. 19, bar 52.
