The missing slur in A (→FE) in b. 540-541 is almost certainly an oversight of Chopin. The next four slurs, written in A, illustrate the difficulties in interpreting handwritten slurs, since each of them manifests a defect (a gap or a shortening), resulting from interruption in the flow of ink. The copyist overlooked 3 out of those slurs (in b. 541-542 at the end of the line of the manuscript), which was completed in GE3. EE unified the slurs: the overlooked slur in b. 540-541 was added and the excessively short R.H. slur in b. 541-542 was prolonged.
