In A (→GE) the articulation-phrasing slur embraces only bar 52. When correcting FE (→EE), Chopin extended it to reach the half of bar 53 and we give that longer slur in the main text.
There is also a slur above the demisemiquaver triplet in the sources. The addition of a long phrasing slur in the proofing of FE reduced the 'triplet' slur to a purely formal function (cf. General editorial principles p. 16), so we remove it from the main text.
