In the main text, we keep the approximate range of the 
hairpin entered into A. The engravers of Chopinesque first editions would often extend hairpins so that they occupy an entire bar; such a procedure was applied in this case by FE (→GE,EE). The difference, as small as it may be, may suggest an erroneous interpretation, particularly at the end of the bar – it is difficult to assume that Chopin would have wanted the crescendos to go beyond the penultimate, highest quaver. See also b. 148.
