The missing slur in FC (→GE) could have been a result of the copyist's oversight; however, according to us, it is much more likely that the slur was added in A (along with 
) after the copy had been already prepared. Anyway, it is difficult to state what Chopin's motivation was at the time of writing a slur in this very place: there is nothing remarkable about this figure; it is just another one among 116 bars provided with such a shape of accompaniment written out in A. Since we adopt FC as the basis for the main text, we do not include this slur, particularly since it does not appear in the repetition of this phrase (b. 246).
