FE1 overlooked L.H. slurs in this bar and the two following ones. Chopin supplemented slurring with one slur encompassing bars 161-164 while proofreading FE2 (→FE3). That slur runs from the beginning of bar 161, contrary to A and similar bars 157 and 159. Hence, the engraver might have misplaced the beginning of slur inscribed by Chopin. The later beginning of slur may be regarded as an equivalent variant. The EE version results most likely from an inaccurate reading of A, despite its conformity to FE2.
