In A the slur in the 2nd half of bar 77 does not reach the end of the group of hemidemisemiquavers. It is most probably an inaccuracy; however, it is unknown whether Chopin wanted to lead it only until the end of the bar or lead it further. The slur at the beginning of bar 78 (on a new page of the manuscript) clearly indicates the latter. The solution adopted in the editions may be considered an alternative interpretation of A, particularly since the slur in bar 77 was corrected in GE1, most probably by Chopin.
