All dynamic markings in bars 1-3, 5-6, 9-11 and 13-15 were added by Chopin in a proofreading of FE (→GE,EE). At the same time, it can be assumed that it was a change of the dynamic concept and not its clarification, which is proved by the parallel change of leggierissimo to brillante in bar 1 and reduction of the number of notes in the chords in bar 2 and analog.
