hairpins falls in another place in each of three sources certainly (A) or possibly (FC and EE) representing the signs written by Chopin. At the same time, while the sign in EE may be considered to be compatible with A, crescendo in FC (→GE) clearly defines another dynamic nuance. In the main text we follow A (→FE), in which the range of the sign corresponds to the hairpins in analogous bars 6-7.
