The exact starting point of the slur in A is unclear. In GE (→FE→EE) it was drawn from the 1st crotchet. The comparison with analogous bars 17, 21 and 29 and the general analysis of the manner of writing slurs in A leads to the conclusion that Chopin almost certainly wanted to embrace only the chords with the slur. The point where the slur ended on the 2nd crotchet of bar 26 seems less controversial, yet even that detail was reproduced inaccurately in GE1 (→FE→EE).
