Chopin doubled the bass progression in the bottom octave in the proofreading of FE (cf. bar 19, in which Chopin also reinforced the bass note, adding an octave). The change, which is certainly to be considered to be final, was also introduced – in the form of added quavers under notes – in EE2 (→EE3).
The missing staccato dot (as well as accent) in FE is most probably a result of an imprecisely performed proofreading.

The change of c to C is certainly a result of Chopin intervention in the last phase of proofreading of FE (→EE). Similarly in bar 160.

The bottom notes of the L.H. octaves were not written out in the sources; they were marked with the use of the con 8va indication. In AsI the octave doubling of the bass line is not indicated at all, which may be only a shorthand notation, because also in the solo part at the beginning of bar 35 there is only A, and it seems unlikely that Chopin started the octave progression with a single note.
