There is no doubt about the moment of breaking the slur in the 2nd half of bar 57, despite differences in the sources. The compatible versions of AW and FE are additionally confirmed by the slurring of AW in bars 7 and 26 and, what is important, by the separation sign added by Chopin in FED between the 8th and 9th quavers in the bar. The slurring of GC (→GE1) is certainly erroneous (inaccurate, sometimes even incongruous slurs are characteristic for Gutmann as copyist). The version of GE2 (→GE3) is a non-authentic attempt to agree the slurs and staccato (portato) dots. It is much more difficult to explain the origin of compatible version of CDP and EE, perhaps it is the original notation of [A], while the separation of slurs in the 2nd half of the bar took place between preparing the copy, being base text to EE, and handing the autograph to Gutmann, whose result was GC.
The issue of number of the portato dots – see the adjacent note.
