The absence of the 
sign in A does not have to be considered to be a mistake – perhaps Chopin did not want to determine the moment of releasing pedal in a place in which most probably it is about gradually suppressing the sound (the so-called diminuendo pedal). The sign added in FE may be authentic, however, according to us, it is to be considered to be an orientation hint only – the pedal can be certainly held longer. In this case, taking into account a possibility of an arbitrary addition of by the engraver or reviser, in the main text we suggest a solution encouraging the performer to creatively look for a way of releasing the pedal, offering the most satisfying dying away of the sound. Cf. the Etude in D
major, Op. 25 No. 8, bars 19-20.
