The version of FE (→EE) is an earlier version, drawn from [A], as it was originally present in GC too. Chopin changed it in GC (→GE), moving the bass motif an octave lower. We give the latter – being the latest – in the main text. It seems to be an improvement due to a more consistent use of the bottom most register of the piano.
In the main text we add cautionary flats before the 1st octave of the bass motif.
