The sources quite clearly differ in the range of 
hairpins, which suggests that they were not copied, but introduced by Chopin himself into three Stichvorlage manuscripts. To the main text we adopt the version of FC, as it is more compatible with the indications of EE – both define the dynamic wave filling four bars, which implies that Chopin wrote such a concept twice. The three-bar version of A must be, however, considered as an equal, alternative concept. The reason for omitting the hairpins in FE is unknown; the engraver's oversight seems to be the most likely answer.
We preserve the position of the signs over the part of the R.H., in accordance with the manuscripts. However, one cannot exclude that the reason for such placement could have simply been lack of space between the staves and moving them to the typical place, as it was performed in GE, is justified.
