When interpreted literally, the slur of A ends over the penultimate semiquaver in bar 72. While the very inaccuracy of notation is hardly disputable, it is uncertain where the slur was supposed to reach, according to Chopin's intention. The interpretation of the editions is certainly possible, yet, according to us, embracing the entire first musical thought (to the F1-F octave in bar 73) is more likely, showing the overlapping segments of this introduction to the 1st theme in the solo part better.
