b. 325-326

in A

Longer  in GE (→FE,IE)

No sign in EE

..

In the main text we reproduce the  hairpin entered into A. In GE (→FE,IE) the mark was arbitrarily extended, as a result of which it spans almost two entire bars (a similar situation is to be found 4 bars later). The absence of the mark in EE is most probably due to the engraver's oversight.

In the main text we add a cautionary  to the first a note in bar 326 and a  to the first d1 note in bar 327.

Slur in b. 328 in A

Slur to b. 329 in GE (→FE,EE,IE)

..

Leading the slur to bar 329 almost certainly resulted from a misinterpretation of A by the GE engraver. In A this place is below bars 320-321, and the L.H. part G1-A1 slur present there could be considered an extension to the discussed R.H. slur in bar 328.

 in GE (→FE,EE,IE)

In GE (→FE,EE,IE) the beginning of the  hairpin was clearly moved towards the beginning of the bar. In this context, it does not influence the performance manner, yet it could suggest, to a certain extent, the range and amplitude of the crescendo.
Similarly, in bar 332.

The missing c3 note in GE (→FE,EE,IE) is most probably an oversight by the GE engraver. In Chopin's autographs, establishing the presence of a middle note of a chord on a ledger line can be problematic; in this case, however, the c3 notehead is very clear, even bigger than e3 (however, the presence of e3 is proven by the very fact of writing a ledger line at this pitch).
