According to us, the fact that the 
mark in FE is more to the right, which may be suggesting that this type of dynamics is in force only just starting from the quaver octave sequence, resulted from an inaccuracy that occurred somewhere between A – [FC] – FE. At the same time, it cannot be ruled out that it was Chopin himself that wrote in [FC] or while proofreading FE1 in this way, since in his pieces we often encounter the manner of writing dynamic markings inside, and not at the beginning of their range – cf., e.g. the autographs of the Etude in G
, Op. 10 No. 5, bar 83, Concerto in E minor, Op. 11, I mov., bar 16 or Prelude in B minor, Op. 28 No. 16, bars 45-46.
