The corrections of placing the 
sign at the end of the bar, visible in A, do not prove, according to us, an intention of an earlier pedal release in this place. Chopin most probably wrote the sign already after the bar line (at the end of the line) and, in order to avoid misunderstandings, he wanted to place it precisely at the end of the bar, yet, as a result of deletions, an illegible inkblot was created. Considering the harmonic pedalling including the entire beats of the bar to be obvious, the composer wrote the necessary sign slightly earlier, at a safe distance from – probably fresh – stain. In GE, the sign was reproduced at the end of the bar and it is also AI, FE and EE that prove the correctness of this way of placement.
