In the main text, we include the correction of the phrasing written by Chopin in FED, which we consider rather a proofreading of the erroneously interpreted slur of [A] than a change of the slurring's concept. At the same time, we interpret the fact of the slurs coinciding at the beginning of bar 264, which could also reproduce the notation of [A] inaccurately, as a continuous slur, like it was written in the first element of the progression (bars 239-240). Both in GE1 (→GE2) and GE3, the shorter slur over bar 263 seems to be an inaccuracy.
See b. 259-261
