EE consistently displays a different slurring of the basic figure in the R.H. in the entire Etude. It is rather a result of a different interpretation of Chopin's autograph by the engraver or copyist than differentiated Chopin notation. In the main text we give the version of two sources – GC and FE – which does not yet mean that the shorter slurs of EE must be considered as inaccurate, particularly considering the fact that neither musical nor pianistic issues give grounds for considering one of these versions to be clearly better. However, the longer slurs are supported by the visible in GC minor corrections of the slurs (e.g., in bar 34), proving the general acceptance of the three-note slurs by Chopin.
In the figures as at the beginning of bar 5 (bars 5-7, 13-15 and 21-23), beginning the slurs in EE under the top note is almost certainly an arbitrary decision of the engraver.
