Different values in FE (→GE,EE

Same as in bar 4, the rhythm's corrections written in FEcor confirm that the crotchets in CLI and Ap is the original version, changed by Chopin in all three analogous places (also in bar 39).

Demisemiquaver in GC (→GE)

Semiquaver in FE & EE

..

It is unclear how the difference in the rhythm in this place was created, however, none of these two versions seems to be erroneous. The notation of EE indicates a possibility of the engraver's error – the bsemiquaver is placed closer to the bar line than the g semiquaver, therefore, it is possible that in the base text to EE the rhythm was the same as in GC. It also cannot be excluded that the additional dot and beam were added in GC by Chopin, although the graphical image of the notation rather does not confirm it. Due to the above ambiguities, in the main text we give the double dotted rhythm, present in the base source (GC).
