In the main text we give the slur of CK (→CB), which is unquestionable in terms of image and music. According to us, it can also be considered an interpretation of the possibly inaccurate slurs of A1 and CJ. The slurring of A1 is generally rather of draft nature – careless and mostly short slurs appear only occasionally.
The absence of the slur in EL does not seem to be an oversight, since this edition is generally devoid of slurs and phrase marks – slurs that are not related to irregular groups are present only in b. 44 (arbitrary) and 47 (authentic). As a result, it could be regarded as a general editorial oversight.
