According to us, the varying ranges of the slurs in bars 373 and 377 may result from misunderstanding of the manner of encompassing the full rhythmic value of the last note with a slur ('slurs-tenuto'), used by Chopin on a number of occasions. The slurs visible in FE would be two attempts to adjust such slurs to the notes in the top voice. In the main text, we suggest reconstruction of such a notation in both bars. The slurs were unified also in GE3, which considered the version of bar 373 to be inaccurate. It can be regarded as an alternative attempt to interpret the slurs of FE.
