The version of GE is probably an authentic original version, corrected by Chopin in FE (→EE) during last retouches. It is indicated by the layout of notes in FE, corresponding to the rhythm of GE and not FE, which may mean that the extending dot of c
2 and the semiquaver beam next to d2 were added only just in print. Such rhythmic variations are frequent in Chopin's works, cf. e.g. the Polonaise in C minor, op. 26, no. 1, bar 61 or the Prelude in C minor, op. 45, bars 67 and 71.
