In A and FC3 (→FE→IE) the upper note of the chord on the second beat of LH is a1. It must have been Chopin's error as proven by on this note in A, which has no justification before a1 and it was omitted in FC3 (→FE→IE). The correct text (with f1) in EE must resulted from the editor's revision. However, it seems little probable in incorrect GE1 - f1 may have been found already in [KF1]. Cf. next annotation.
A certainly long accent in A was copied wrongly - as a short one - in FC3 (→FE→IE) and EE but omitted in GE. Cf. bars 164-178 .
